Many attempts have been made at computer simulation of crashworthiness. These have, in most cases, consisted of models composed of concentrated masses and nonlinear springs. Such methods exhibit several drawbacks. Tremendous effort is required to accommodate the characteristics of the masses and springs as the car body undergoes structural changes, and to implement feedback of design changes and modification in these calculations. This paper will present the results of finite element analysis (FEA) on predictions of large scale frontal and rear crashworthiness. This approach makes more accurate and practical modeling possible. The results of these calculations compare very favorably with experimental observations. As an example, of how the method is applicable to various fields the calculation of large deformation of a curved frame and bumper are described.
