Finite Element Analysis of Automotive Structures Under Crash Loadings. Volume II. Technical Report.

摘要

A research project was undertaken to develop a finite element computer program for use in the dynamic analysis of vehicle structures,including sheet metal,in a crash environment. This research program involved the following major tasks: A technique was developed for the finite element analysis of the dynamic response of plate beam structures involving very large displacements and rotations and elastic-plastic material behavior. The principal feature of this technique involves the decomposition of the element displacement field into rigid body components and deformation components thus allowing the use of a small deflection formulation in the analysis.
