... FINITE ELEMENT METHODOLOGY The major catalyst for this rapid evolution has been the development of efficient finite element methods for nonlinear mechanics. The past two decades have seen the emergence of powerful nonlinear finite element algorithms and rapid advances in the fundamental understanding of nonlinear mechanics and material behavior.

... All of these difficulties must be resolved effectively to make computer prototype testing a practical tool. The efficient implementation of nonlinear mechanics algorithms to new computer architectures will require careful coordination between the mechanics modeling processes and the computer architecture.
