VALIDATION AND APPLICATION OF THE WRECKER NONLINEAR FINITE ELEMENT PROGRAM IN ANALYZING VEHICLE SIDE STRUCTURES. VOLUME I: SUMMARY REPORT

WRECKER, a new computer program developed to calculate the large deformation response of car bodies during impact, has previously been evaluated only by using idealized checkout problems. The purpose of this project is to determine the program's strengths and weaknesses in analyzing actual automotive structure. Toward this end, a finite element model of a Volkswagen Rabbit side structure under federal compliance test (FMVSS 214) quasi-static loading is developed. The following capabilities were added as required to strengthen the program: (1) a redimensionable version of the code, (2) nodal contact capability, (3) a three-node beam element, (4) various input and output improvements, and (5) three preprocessors to aid in preparing the input data.
