Abstract: The effects of a bottom-mounted rectangular block on the sloshing characteristics of the fluid in rectangular tanks are investigated using the linear water wave theory. For the sloshing analysis the velocity potential is decomposed into those for the wall-induced waves and the reflected, transmitted and scattered waves by the block. The reflection and transmission coefficients related to the block are determined using the continuity conditions of mass flux and energy flux on common vertical boundaries of the fluid regions and the boundary conditions on both sides of the block. Verification of the present analysis method is carried out by comparing the results with those by other methods. The analysis results indicate that the size and location of the block significantly influence the sloshing frequencies and mode shapes. In general, sloshing frequencies reduce as the block becomes tall and wide. The variations of the sloshing frequencies and mode shapes due to the block are found to be more sensitive in broad tanks than in tall tanks. The hydrodynamic pressure exerted on the tank wall and the block changes significantly as the block becomes large and moves toward the wall.

Abstract: To obtain accurate time-dependent temperature distribution in fusion reactor nuclear components, a nuclear-thermal coupled calculation code system has been developed. The code system couples the two-dimensional radiation transport code DOT -3.5 and a finite element non-linear temperature analysis code ADINAT. Using this code system, the time-dependent temperature distribution in a shielding blanket of a fusion experimental reactor similar to ITER has been calculated for various conditions. The code system has been further extended to calculate thermal stress, by coupling the structural analysis code ADINA. (8 refs.)

Abstract: Composite materials are being investigated in advanced technology test beds for use in future armored vehicles. We are particularly interested in the response to impulsive loading for which the knowledge of natural frequency behavior is important. In this paper, we investigate the natural frequency analysis capabilities of the multilayered shell element of the ADINA finite element code as applied to laminated composite beams and plates. Results are compared to those published in the literature or those derived from exact solutions. The ADINA shell element employs a first-order shear deformation theory, and the results are found to agree well with other first-order theories. Although ADINA does not allow for a direct method of incorporating a shear correction factor commonly used in first-order theories, it is demonstrated how this can be included by modifying the material properties.

Abstract: ADINA is used as the primary design tool in engineering of the tether (tendon) top connector assembly (TCA) for a tension leg platform (TLP). This paper focuses on how analyses performance requirements in a large offshore development project were met using the capabilities of ADINA. A design procedure for the TCA of a TLP is described. In order to obtain the specified accuracy an extremely dense mesh is required, which leads to large numerical models. As shown in both linear elastic and elasto-plastic analyses the load transfer distribution and stress concentrations, and thereby fatigue life, is strongly affected by machining tolerances for the TCAs threaded connection. As finite element analyses (FEA) play a major role in the integrated design development of the TCA, general industry policy of reduced lead time (RLT) in engineering becomes a special requirement of FEA engineers. Use of ADINAs new iterative solver and new W function contact algorithm made RLT possible still maintaining required accuracy in accordance with mesh convergence tests. (21 refs.)

Abstract: An experimental program has been initiated to measure the response of Timetal(R)21S plates and SCS-6/Timetal(R)21S metal matrix composite (MMC) plates monotonically loaded through a pinned connection at high temperature. A coordinated analytical effort has also been started to model these experiments using the ADINA finite element package and a modified version of the user-defined material module of Kroupa (1993) which incorporates a Bodner-Partom viscoplastic model. Results are presented for the first part of this analytical study, which considered the response of monolithic Timetal(R)21S plates in order to determine the importance of various factors for incorporation into more complex analysis of the MMC plates. Studies were conducted to assess the viability of efficient approximate boundary conditions; the importance of residual thermal stresses induced during heat up prior to mechanical loading; and the accuracy of the material model. Results indicate that detailed modeling of the pin-plate contact surface is required to achieve high accuracy; thermal residual fields in the plate and pin may be neglected; and refinement of the constitutive model is required for improved accuracy.

Abstract: Most grinding problems cannot be solved analytically, therefore extensive numerical solutions are required by using appropriate numerical techniques such as the finite element method (FEM). In this study, the well-known finite element software, ADINA, was used to predict the phase transformation of a workpiece subjected to surface grinding. The process was considered to be two-dimensional and the properties of the workpiece material were temperature dependent. To gain practically acceptable results, the induced temperature field and the associated phase transformation were analysed by different element meshes. Some efficient solution strategies were proposed to obtain reliable predictions for different grinding conditions and workmaterial properties. The user coding facilities of the code were used to achieve the above performances. (16 refs.)

Publisher: Pergamon Press Inc

Abstract: The behaviour of structural elements subjected to cyclic loading conditions is described by overlay models and simulated using standard finite element programs. The material model is established by parallel connection of several finite elements, each describing elasto-plastic material behaviour with kinematic or isotropic hardening and sharing the same geometrical position. The death or birth option, respectively, is used to simulate the yielding condition with a higher and lower yielding stress. A method estimating the material parameters is discussed. Results found by using ADINA 6.0 for the analysis of a cylindrical structural element under cyclic axial tension are presented. The effect of locally varying material parameters is discussed.

ADINA applied toward simulation of progressive failure in underground mine structures

Abstract: The U.S. Bureau of Mines (USBM) conducts research to develop simple and practical computer-based tools to assist mine planners in assessing the structural stability of underground mine structures. One area of research is focusing on developing a numerical procedure that will anticipate rock mass behaviour surrounding underground mine openings prior to and during actual mining. This paper briefly overviews our experience with existing ADINA material models, presents an example of how two-dimensional boundary-element models are coupled with two-dimensional finite-element models to simulate an approximate three-dimensional situation, and demonstrates the use of a simplified progressive failure procedure. Outputs from plan-view, linear-elastic, boundary-element models executed at different mining stages are used as input to detailed, section-view, finite-element ADINA models to estimate to what degree and extent the immediate roof and floor strata and the coal pillar ribs surrounding an excavated area will weaken or fail for a given set of mining parameters. Using a pseudo-elastic approach, elastic rock mass properties are continually updated as different zones are predicted to fail. The procedure is relatively easy to use and is being designed to work interactively with the user. Inputs include parameters easily obtained from the field and rock mechanics laboratories. Specialized preprocessing and post-processing PC-based graphics software tailored specifically to mine geometries has been developed, and is described. Examples of computer-generated output from sample models representing typical mining situations are presented and results discussed. (15 refs.)

Crack growth evaluation of a multimaterial CS-type specimen

Abstract: During the German HDR Safety Program the integrity of a reactor pressure vessel was studied intensively during a pressurized thermal shock loading. As a part of the work this paper presents a stable crack growth evaluation for a side-grooved, multimaterial CS-type specimen, which was detached from the inner surface of the HDR reactor pressure vessel. The specimen was composed of ferritic base material and two austenitic cladding material layers. The specimen was tested at the Fraunhofer-Institut fur Werkstoffmechanik, Freiburg, Germany, and revealed an extremely nonuniform stable crack growth distribution along the crack front. Elastic-plastic finite element analyses were carried out using the 85-version of the ADINA code. For crack growth simulation a separate subroutine package IWM-CRACK linked with ADINA was used. Additional J-integral calculations were carried out based on the ADINA results, using the VTTVIRT code in order to study the path dependence of the J-integral. The crack growth was controlled by Jr curves, while actual measured data were available only for the base material, and hypothetical Jr curves were applied for the two cladding layers. The calculated maximum load was slightly higher than the maximum load measured in the test. The crack growth was relatively well simulated in quality. The slight numerical discrepancies at some locations along the crack front were consistent with extreme local material brittleness, which was clearly underestimated by the assumed material properties.

Finite element modeling of damping in constrained layer composite structures induced by inplane loads using ADINA

Abstract: Passive damping for inplane axial loads can be created by special design of fibrous composites with intermediate viscoelastic plies. Conventional constrained layer damping takes place due to free edge transverse shear in the viscoelastic layer. A proposed segmented constrained layer damping is reviewed. Implementing a chevron pattern of segments for each lamina allows for more lateral motion and potentially more damping. The finite element package ADINA is used to model the composite laminates and, using the modal strain energy method, investigates damping mechanisms. A parametric study of modeling parameters is presented demonstrating the phenomena by which damping is occurring and the relative importance of each of the design criteria. The segmented constrained layer damping is found to be advantageous when small segment aspect ratios are employed. (12 refs.)

Abstract: Immediate post-operative stability is critical for the long-term success of biological implant fixations. Excessive motion at the bone-prosthesis interface is known to inhibit bone ingrowth and thereby cause failure of the fixation. In the present study, relative displacements between the host bone and the tibial component of total knee implants were evaluated, and the effect of the method on the immediate post-operative fixation was assessed using a three-dimensional friction-contact finite element model of the tibia-prosthesis unit and ADINA. Three types of fixations were considered: (1) close-fit; (2) press-fit; and (3) screw fixation. For the validation of the model, the predictions were compared with measurements in four human cadaveric specimens. The results of the study showed that, (i) friction affects significantly the magnitude of the interface relative displacement, (ii) the relative displacements are similar for close-fit and press-fit fixations, and (iii) the relative displacements are significantly less in comparison of those for press-fit fixation. Therefore, use of screws for immediate post-surgical fixation is likely to result in enhanced bone ingrowth. (36 refs.)
