Abstract: An example will be shown that ADINA was applied to thermal stress analysis of a concrete dam. The characteristics of thermal stress analysis of a mass concrete structures that the finite elements should be added according to the casting schedule of concrete and the elastic modulus of concrete should be increased with time. The user's routine was developed to calculate thermal stress in concrete structures. As an example, temperature and stress distributions were simulated in a concrete dam which was constructed by our company.

Abstract: For efficiency, a finite element model should give sufficiently accurate results with the minimum number of degreesoffreedom. It is thus important to assess the solution accuracy and sensitivity with respect to the loading and structural details. This paper is specifically concerned with the accuracy of displacement predictions from finite element models of plates and stiffened panels subjected to airblast loads. In particular, the effects of boundary condition and loading details on the displacement response are assessed.

Abstract: A postprocessor program for ADINA shell elements has been developed to evaluate Jintegral values as crack driving forces for ductile fracture mechanical problems with wall penetrating cracks of regular simple shape. The performance and accuracy of this procedure have been proved on several pipe component test cases with pressure, bending and thermal loads. The method seems to be well suited for the assessment of such cracks against stable crack initiation. As a rule the results with shells are calculated with less overall expense than equivalent threedimensional continuum element models would require.

Abstract: A threedimensional nonlinear finite element analysis of a cemented femoral component in which the component was partially debonded from the cement mantle was used to assess the effects of debonding on stresses in the cement. Three cases of partial cementmetal debonding were modelled with debonding of the proximal portion of the implant down to a horizontal plane which was 35, 62.5, or 82.5 mm below the prosthesis collar. Each situation was studied under loads simulating both gait and stair climbing. Also, complete debonding between the implant and the surrounding cement mantle was modeled for loads simulating pit. Under stair climbing loads with partial cementmetal debonding, hoop stresses of 1318 MPa were observed in the cement at the cementmetal interface at the proximal posteromedial corner of the implant. Similarly, in stair climbing, the maximum principal stresses in the cement were also adjacent to the proximal posteromedial region of the implant. These stresses were compressive and increased from 15 MPa with fully bonded interfaces to 48 MPa with debonding down to 82.5 mm below the prosthesis collar. Under gait loads, complete debonding caused high compressive stresses up to 34.9 MPa in the cement distal to the prosthesis tip.

Abstract: The ADINA program has been used with three progressively more accurate loading functions to model the dynamic response of a plate. The calculations simulated the response of a 19 mm thick aluminum plate, clamped over a circular opening 914 mm in diameter, subjected to the blast from an explosive charge suspended 645 mm over its center. The loading functions were based on prior hydrocode calculations of the detonation flow using successively refined computational grids. The influence of clamped edge conditions on the response was bracketed by allowing no sliding and frictionless sliding. Calculations were performed using a linear analysis, a material nonlinear analysis with kinematic hardening plasticity, and a combined material and geometric nonlinear analysis. The deflection histories obtained with the three methods of analysis using the three progressively refined loading functions for the two bracketing boundary conditions were compared. The response was found to be sensitive principally to the total impulse delivered to the plate, though the influence of loading details was detected. Despite a significant amount of plasticity, the deflections were predominantly influenced by the strong coupling between the membrane and transverse deformations, resulting in the response being noticeably affected by boundary modeling and indicating a need to use the geometric nonlinear method of analysis.

Abstract: In the modelling of elastomeric structures, soft composites, tires, etc., generally large deformations and significant localized material nonlinearity are encountered. During the solution of finite element models of such structure, indefinite stiffness characteristics are often encountered. Such behavior may be an outgrowth of a variety of factors, i.e. real physics, model degeneracies, boundary conditions, etc. This paper revisits various causal factors effecting definiteness. These considerations will help in modifying and relaxing some of the current convergence requirements on the global stiffness. This in turn, will result in a solution of more realistic models with potentially significant savings in CPU time.

Abstract: The objective of this investigation is to develop an analytical model to evaluate the seismic performance of the active links in eccentrically braced frames. The ADINA finite element computer code is used to gain insight into the behaviour of the links under cyclic loading. An available experimental setup and testing program was modelled. It was found that it is possible to develop a simple yet effective finite element approach to model the very complex behaviour of the links. Comparison between analytical predictions and available experimental results showed good agreement.

Abstract: Deployable structures are prefabricated space frames that can be stored and transported in a compact folded configuration and then deployed rapidly into a load bearing configuration. The structures are stable and stressfree in the folded and the deployed configuration, but exhibit a highly nonlinear behavior during deployment. Therefore, their design process should include simulation of their response in two phases: in the deployed configuration under service loads, and during deployment. The first phase involves linear analysis while the second one requires a geometrically nonlinear finite element formulation. Both simulations can be very demanding in terms of computer storage requirements as the number of degrees of freedom increases. In addition, the nonlinear analysis is quite expensive because of the large number of load steps that are necessary in order to trace the complete loaddisplacement path. This paper first describes a set of numerical models that were used to simulate the exact structural behavior using the finite element program ADINA. Then, some simplified analytical and numerical models are proposed that can be applied in the preliminary design stage, or even for final design, in order to obtain approximate but satisfactory results at a much lower cost.

Abstract: In this paper we present some experiences with the use of the conjugate gradient and GMRES iterative methods for the solution of large sparse systems of equations as recently implemented in ADINA and ADINAF for structural and fluid flow problems. The conjugate gradient method preconditioned with the incomplete Cholesky decomposition is used for the symmetric positive definite systems resulting from structural problems. For fluid flow problems, the systems of equations are nonsymmetric and indefinite. For these systems, the biconjugate gradient and GMRES algorithms with preconditioning by incomplete LU factorization are used. The performance of the iterative methods is compared with the direct solution methods. The results from our numerical experiments show that the use of these iterative methods for large sparse systems can lead to significant reductions in storage requirements and computation times, especially for nonlinear structural dynamics problems and threedimensional problems in general.

Abstract: A number of new systems technologies have been released over the last year which significantly affects the possibilities for designing finite element analysis facilities. Examples include workstations which have nearly the power of Cray 1 computers, virtual file systems which provide the equivalent of gigabytes of disc storage, high performance color hard copy capability, and advances in the software interoperability layers, such as XWindows, postscript, and NFS, which provide the opportunity for increased integration of these systems opportunities. The result is the opportunity to design finite element facilities which are dramatically different than facilities of even five years ago, and which offer the potential of significant improvement in analyst productivity. These technologies will be discussed, and the results of the internal testing of these technologies at Texas Instruments will be described. A reference facility with migration opportunities to the new technology will be detailed. Finally, thoughts on future systems technologies, and their impact on finite element facilities, will be discussed.

Abstract: In this study, the stresses within the cement and at the cementmetal interface have been studied using a largescale linear finite element analysis. Also, to assess the effects of cementprosthesis debonding, a 3D contact study was conducted which assessed the effect of several different areas of debonding between the prosthesis and the cement. The results of finite element analysis showed that the most likely sites for failure initiation are in the proximal anteromedial region and at the distal prosthesis tip. The loading situation which appeared to put the interface in the most danger for failure is that encountered in stair climbing. The stresses during normal walking did not seem as critical. Simulation of cementmetal debonding showed that a drastic increase in cement stresses occurred under both gait and stair climbing loads, and that stair climbing loads also produced much higher stresses with debonding. The effect of pores which often occur in bone cement was assessed using an analytical elasticity solution for a spherical void in an infinite medium, which allowed a calculation of the maximum tensile stress at the surface of a pore. These stresses were sufficient to initiate fractures near the distal tip of the implant in many cases, and near the proximal medial region of the implant in stair climbing. This study concurs to a remarkable degree with a study of wellfunctioning total hip replacements recovered at autopsy. The initiating failure events seen in the retrieved femoral components matched closely with the predicted areas of failure initiation. The conclusions of the study were that the cementprosthesis interface should be strengthened, porosity in bone cement should be minimized, and that total hip patient should not use their prosthetic hip when climbing stairs.

Abstract: The paper deals with the updating of computational models for elastomechanical vibrating structures. The updating procedure is based on system identification techniques using an incorrect model on the one hand and measured data of the real system on the other. Some approaches with different types of measurement data are discussed. For practical realization the finite element program ADINA is combined with a nonlinear optimization algorithm and measured transfer functions are used for the correction of the design parameters. The application of the procedure is demonstrated by means of three examples.

Abstract: This paper presents a comprehensive finite element study using the ADINA code with an objective towards developing a procedure for incorporating the effect of thermal/residual stresses in the Jintegral elasticplastic estimation method. Thermalelasticplastic finite element studies have been carried out for several twodimensional crack geometries including the centercracked plate, singleedge cracked plate and cylinders containing axial and circumferential flaws. Analyses are based on the J_{2} flow theory of plasticity and include material strain hardening. Results are obtained for various fracture parameters of interest such as J, COD and mouthopening displacement (MOD). The Jintegral is calculated by a virtual crack extension method, modified for thermalelasticplastic crack problems. It is shown that the effect of thermal/residual stresses is negligibly small when fully plastic conditions are achieved. Based upon these observations and using the superposition principle for the stress intensity factor K_{I} under smallscale yielding, a modified procedure for estimating fracture parameters under thermalelasticplastic conditions is formulated. The results thus obtained are compared against detailed finite element calculations, with an observed excellent agreement between the two sets of results. Various aspects of the cracktip behavior under the conditions of thermalelasticplastic deformation are also discussed.
