VECTORIZATION AND PARALLEL PROCESSING STUDIES USING A CRAY X‐MP IN NON‐LINEAR COMPUTATIONAL SOLID MECHANICS

Z.P. WANG, D.R. HAYHURST, B.A. BILBY, I.C. HOWARD

Two non‐linear finite element programs have been restructured by using vectorization techniques in order to run efficiently on the Cray X‐MP/416. One of them has also been…

CURVILINEAR COMPOSITE TRIANGULAR ELEMENT OF CLASS C

GEORGE MEJAK

A triangular composite element with 15 degrees of freedom is introduced. It is shown that after an appropriate modification of the Zlámal coordinate transformation this element…

SOME BASIC FINITE ELEMENT ANALYSIS OF MICROVOID NUCLEATION, GROWTH AND COALESCENCE

B. BENNANI, P. PICART, J. OUDIN

Microstructure void volume fraction is taken into account in finite element models developed for large strain elastoplastic problems. Void nucleation rate is related to matrix…

AEROTHERMODYNAMIC ANALYSIS FOR AXISYMMETRIC PROJECTILES AT SUPERSONIC/HYPERSONIC SPEEDS

MICHAEL J. NUSCA

An aerothermodynamic design code for axisymmetric projectiles has been developed using a viscous‐inviscid interaction scheme. Separate solution procedures for the inviscid and the…

A COMPARISON BETWEEN THE GENETIC ALGORITHM AND THE FUNCTION SPECIFICATION METHODS FOR AN INVERSE THERMAL FIELD PROBLEM

R.L. WOOD

In principle, it is possible to apply genetic algorithms (GAs) to the solution of inverse problems in the simulation of manufacturing processes. In this context, an inverse…

INDUSTRIAL PRODUCTS FORMABILITY ANALYSIS USING 3D SHEET METAL FORMING SIMULATION

S. AITA, E. HAUG, F. EL KHALDI, D. LEFEBVRE, E. DI PASQUALE

A sheet metal forming simulation code has been developed, based on the explicit time integration scheme and Mindlin shell theory. It has been used for the analysis of a number of…
