Abstract : This paper describes a hybrid approach to predicting the crash behaviour of an impacting structure which is tailored to velocities which do not exceed 30-40 miles/h. The method involves using component and joint test data (as data base) in conjunction with coarse finite element idealisation to determine collapse mechanism sequence of the collapse and collapse speed of an impacting structure.
