An advanced recurrent artificial neural network (ANN) is used to store the nonlinear dynamic characteristics of the vehicle structure. Hundreds of impact scenarios can be performed quickly with much less cost by using the trained networks. A finite element model for a simple box beam with rigid mass attached to it was developed to represent a general crushable object. The simulation results were performed by impacting this model into a rigid wall with different initial velocities. The results indicated that the recurrent ANN can accurately capture the frontal crash characteristics of any impacting structure, and predict the crash performance of the same structure for any other crash scenario within the training limits.
