PURPOSE AND SCOPE

The purpose of this document is to illustrate, by detailed example, the most important aspects of V&V described in the Committee's framework document, Guide to Verification and Validation in Computational Solid Mechanics (V&V 10).V&V10 intentionally omitted examples, as its purpose was to provide "a common language, a conceptual framework, and general guidance for implementing the process of computational model V&V," an already broad scope for a 27-page consensus document. The present document is the first in a series of more detailed and practical ones the Committee has planned to incrementally fill the gap betweenV&V10 and a set of recommended practices.

To appeal to a broad range of mechanics backgrounds, a cantilever beam problem has been selected to illustrate the following aspects of V&V. The numbers in parentheses are references to sections and paragraphs in V&V 10 as follows:

(a) validation plan (para. 2.6)

(1) validation testing (para. 2.6.1)

(2) selection of response features (para. 2.6.2)

(3) accuracy requirements (para. 2.6.3)

(b) modeling development (section 3)

(1) conceptual model including intended use (para. 3.1)

(2) mathematical model (para. 3.2)

(3) computational model (para. 3.3)

(c) verification (section 4)

(1) code verification: comparisons using analytical solution (para. 4.1)

(2) calculation verification: mesh convergence (para. 4.2)

(d) parameter estimation (para. 3.4.1)

(e) validation (section 5)

(1) validation experiments (paras. 5.1 and 5.2)

(2) comparison of experimental results and model prediction (para. 5.3)

(3) decision of model adequacy (para. 5.3.2)

(f) uncertainty quantification (para. 5.2)

(g) documentation (paras. 2.7, 4.3, and 5.4)
