During the past couple of years, a committee under the auspices of the ASME Codes and Standards division has been formed and are meeting regularly. The purpose of the committee is to develop and publish a set of documents that describe a common process for verification and validation of computational solid mechanics models. There are many issues under discussion and many concepts under debate. In this paper we will present some the major concepts and the differing viewpoints focusing on the concept of validation and relate this to the automotive industry in particular.

Verification and validation (V&V) is an enabling methodology for the development of models that can be used to make engineering predictions with high confidence. Model V&V procedures are needed by government and industry to reduce the time, cost and danger associated with component and full-scale testing of products, materials, and weapons. The development of guidelines and procedures for conducting a V&V program are currently being defined by a broad spectrum of researchers. This paper briefly reviews the main concepts involved in V&V and then focuses on the critical role that nondeterministic analysis plays in the V&V process.
