Crush analysis of automobiles is the simulation of a slow, dynamic (virtually static) process. In general, only codes based on explicit dynamic analysis procedures have been employed to analyze a crush response. These analyses are computationally expensive, require tuning of the model, and do not accurately represent the actual physics of the crush process. ADINA can be employed to perform crush analyses using the implicit dynamic (practically static) analysis procedures, thereby accurately representing the actual physical process. The solution of the Ford Windstar shown here was solved using ADINA on a Silicon Graphics O2000 machine in about 24 hours of computing time.
