FINITE ELEMENT ANALYSIS OF AUTOMOTIVE STRUCTURES UNDER CRASH LOADINGS. VOLUME I. SUMMARY

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. A computer program was developed incorporating this analysis procedure for beam and plate elements and rigid links together with appropriate time integration procedures and material property descriptions.
