Use of ADINA-T to calculate soil consolidation

Yung, Francis P. K. (Univ of Alberta, Edmonton, Can); Morgenstern, Norbert R. Source: Computers and Structures, v 26, n 1-2, 1987, p 153-164

ISSN: 0045-7949 CODEN: CMSTCJ

Conference: Nonlinear Finite Elem Anal and ADINA, Proc of the 6th ADINA Conf, Jun 10-12 1987, Cambridge, MA, Engl

Abstract: The use of ADINAT in the calculation of one-dimensional consolidation is evaluated. Both linear and non-linear analyses are considered with finite strain and self-weight effects included in the non-linear analyses. Examples are given to illustrate the calculations of pore pressure variation with time and comparisons are made with existing published solutions. Good correspondence is found, leading to the conclusion that ADINAT provides a powerful tool to solve a wide variety of multi-dimensional uncoupled non-linear consolidation problems. (12 refs.)

Abstract: The updated Lagrangian Jaumann formulation is used for the analysis of an elastic closed strain path involving stretching and shearing. The analytical stress solution for each phase of the strain path is given and the final stresses at zero strain are calculated. We do not present any new concept or procedures but study an interesting example solution that gives insight into the use of the updated Lagrangian Jaumann formulation. (5 refs.)

Abstract: A finite element analysis tool which has been specifically developed for modeling the thermoforming and blow molding of 2-D and axisymmetric shapes is described. Both the theoretical background and the finite element implementation is included. The hot polymer is modeled as a nonlinear elastic, incompressible, membrane. Results from finite element calculations are compared with theoretical predictions for selected problems and are shown to be in excellent agreement. In addition, comparison between analysis and experiment is given for a particular example of thermoforming. (18 refs.)

Abstract: The effects of free field motion computation procedures on the response of soil-structure interaction systems is examined by employing the finite element method. The results indicate that under certain conditions the analyst should provide specific boundary conditions in order to preserve the free field motion character. In the event that such steps are not taken one should expect significant differences in the computed structural motions. (22 refs.)

Abstract: A case study is presented on the use of the finite element analysis program, ADINA, as an aid in the design of an elevator shaft to be located in the close proximity to an existing penstock tunnel. The excavation for the shaft may create over-stressing or excessive displacements of the existing tunnel lining which would be undesirable. ADINA was used to find stress and displacement vectors. Difficulties of analyzing a large sized 'ADINA' model to find those vectors were resolved by using PATRAN software and mixing of the linear and nonlinear elements. (20 refs.)

Abstract: The state of deformation, strain and stress of cylindrical steel specimens under cyclic thermal loading is studied both experimentally and numerically by the finite-element package ADINA/ADINAT. Specimens of the same initial geometry subjected to the same thermal treatment display markedly different behavior depending on their composition. The monotonic alteration of the geometry can be partially explained as the consequence of the accumulation of plastic strains. (12 refs.)

Abstract: A series of pipe rupture tests has been performed at the Japan Atomic Energy Research Institute (JAERI) to demonstrate the safety of primary coolant circuits in the event of pipe rupture in nuclear power plants. Pipe whip tests and jet discharge tests have been conducted under boiling water reactor (BWR) and pressurized water reactor (PWR) loss-of-coolant accident (LOCA) conditions. The present paper describes the experimental and analytical results of the pipe whip tests performed under PWR LOCA conditions using 4, 6 and 8-inch test pipes. The tests were carried out at an initial pressure and temperature of 15. 7 MPa and 325 degree C, respectively. Moreover, a dynamic analysis of pipe whip tests was carried out using the general purpose finite element program ADINA. (10 refs.)

Conference: Nonlinear Finite Elem Anal and ADINA, Proc of the 6th ADINA Conf, Jun 10-12 1987, Cambridge, MA, Engl

Abstract: ADINA finite element solutions for the local buckling behavior of C-shaped lipped channel cold-formed sections, with and without a large web opening, subjected to concentric axial load are presented. Isoparametric shell elements are used to model one-quarter of the sections. The web opening is generated using element birth/death option. The cold-formed steel has been treated as multi-linear elastic-plastic material with von Mises yield criterion. Material non-linear only analysis and material and geometrical non-linear analysis results are presented and compared with the experimental results. The ultimate loads are correctly predicted with the material and geometrical non-linear analysis. However, the predicted sub-ultimate behavior does not agree well with the experimental results, perhaps due to the inherent imperfections. (12 refs.)

Abstract: The vibration response of a heat exchanger tube row subject to cross flow is studied. The FE-code ADINA is employed and the fluid forces acting on the tubes are modelled by user-supplied load routines. The fluid forces depend on the current state of motion as well as on the flow velocity and the fluid density. Stability limits are found where the tube displacements are growing monotonically. Nonlinear fluid forces could be easily implemented as well as other nonlinearities such as gaps between tubes and baffles etc. The model looks promising as it shows good agreement with earlier published results. Future developments are outlined. (26 refs.)

Die tool dimensioning by finite element method

Aren, B. (Lulea Univ of Technology, Swed); Nilsson, A. Source: Powder Metallurgy, v 30, n 2, 1987, p 87-96

ISSN: 0032-5899 CODEN: PWMTAU

Abstract: Stress and strain are studied using the finite element method in the dimensioning of prestrained die tools for powder compaction. The die geometry has been varied and the die has also been subjected to different types of load. The study shows that the mean pressure transverse to the pressing direction is a dimensioning factor, but that the distribution itself is not very important. For a linear pressure distribution, the stress and strain within the die will differ little from results produced under the assumption of an exponential pressure distribution. Attention is also paid to the possibilities of treating the three-dimensional situation in a real die by different methods of two-dimensional FEM analysis. (7 refs.)

Abstract: Nonlinear soil-structure interaction effects are modelled by using a time domain formulation including special interface elements between soil and foundation, an elastic-plastic cap material model for the soil and absorbing infinite elements for the simulation of the unbounded region in the far field. The necessary computational procedures have been implemented in the ADINA computer code and the applicability is demonstrated by numerical simulations on a typical engineering problem. (17 refs.)

Abstract: A single degree-of-freedom elastodynamic analysis of the response of a rectangular plate subjected to an explosive blast has been conducted assuming a Navier form of displacement function and a modified Friedlander reflected blast overpressure loading which exponentially decays with time. Closed-form solutions of dynamic displacements, velocities and accelerations of the mid-point of the plate centered above an explosive charge at a specified standoff are obtained. Comparison of the peak displacements from the analysis with the predicted results from the ADINA finite element code indicates excellent agreement for the linear elastic dynamic case. These results also indicate that a nonlinear analysis of the plate should be performed; therefore, some results of elasto-plastic analyses using ADINA are also presented. (18 refs.)

Thermo-mechanical analysis of dry sliding systems

F.E. Kennedy, S.Z. Hussaini

Thayer School of Engineering, Dartmouth College, Hanover, NH 03755, U.S.A.

Computers & Structures, 26:345-355, 1987

Abstract: This paper discusses the numerical analysis or temperatures and stresses near the regions of contact between flat sliding rings, such as the seal rings of mechanical face seals. Of particular interest were rings having a hard, wear-resistant coating on a ductile metallic substrate. The temperature distribution in the sliding contact region was determined using a specially-developed finite element program, and that temperature distribution was used, along with mechanical normal and tangential contact tractions, as input to an ADINA-based thermo-elasto-plastic analysis of stresses and deformations. It was shown that frictional heating is the dominant contributor to high localized temperatures and stresses around the contact region, that plastic deformation can occur in the region, and that thermally-induced deformations and stresses can be a major reason for coating failure. The influence of coating and substrate properties, as well as coating thickness, on the results and on potential failure mechanisms was studied.
