Uncertainty Quantification in Verification and Validation of Computational Solid Mechanics Models - Example

Abstract

Verification and validation (V&V) are processes designed to assure, with quantifiable confidence, that the computational models we use, solve the problems they are meant to solve, and that the models adequately represent the structures they are meant to model. The American Society of Mechanical Engineers (ASME) Standards Committee on Verification and Validation in Computational Solid Mechanics (PTC 60/V&V 10) has approved a Guide for performing V&V [1]. The Guide is brief, and does not provide specific methods for the performance of model V&V, therefore, subcommittees have been formed to develop documents specifying methods for accomplishing the various activities of V&V. One of these subcommittees was formed to develop the “Uncertainty Quantification Supplement to the ASME V&V 10-2006 Guide.” The talks in this special session describe some of the activities associated with uncertainty quantification in V&V. This paper presents an example used to illuminate some of the tools and measures developed in the other papers in this sequence. The example describes experimental results and model predictions.
