REFINEMENT OF FINITE ELEMENT ANALYSIS OF AUTOMOBILE STRUCTURES UNDER CRASH LOADING. VOLUME I. SUMMARY REPORT

A finite element computer program for use in the static and dynamic analyses of vehicle structure, including sheet metal, in a crash environment was developed in this research project. The developed computer program consists of the following features: large displacement, nonlinear static and dynamic, and elastic and plastic including strain-rate effect; with plate, three-dimensional beam and spring elements, and rigid links and a variety of three-dimensional beam end conditions; options of using either the explicit or implicit time integration procedures; and options of specifying stress, mass and center of gravity, and energy output.
