Comparison of the V&V10.1 and V&V20 Modeling Error Quantification Procedures for the V&V10.1 Example (original) (raw)

Abstract

The determination of the transverse tip deflection of an elastic, hollow, tapered, cantilever, box beam under a uniform loading applied over half the length of the beam presented in the V&V10.1 standard is used to compare the application of the validation procedures presented in the V&V10.1 and V&V20 standards. Both procedures aim to estimate the modeling error of the mathematical/computational model used in the simulations taking into account the variability of the modulus of elasticity of the material used in the beam and the rotational flexibility at the clamped end of the beam. The paper discusses the four steps of the two error quantification procedures: (1) characterization of the problem including all the assumptions and approximations made to obtain the experimental and simulation data; (2) selection of the validation variable; (3) determination of the different quantities required by the validation metrics in the two error quantification procedures; (4) outcome of the two v...
