1. A computer method of material modeling for crash test dummy finite element models, said method comprising the steps of: providing a computer; making a material card for the material using the computer; applying the material card to validate a finite element model of a crash test dummy component using the computer; determining whether the finite element model is acceptable; ending the method if the finite element model is acceptable; and adjusting a relative volume range for the material to make the material soft or stiff if the finite element model is not acceptable.
