Verification and validation of models used in computer simulations of roadside barrier crashes

The Finite Element Method (FEM) is now regularly used by engineers to analyse the crashworthiness performance of roadside safety barriers. In particular, the improvements in nonlinear Finite Element (FE) codes and the available access to supercomputing facilities have now allowed engineers to simulate in detail crash tests between vehicles and roadside safety barriers. Computer FEM simulations allow investigating the performance of new designs or retrofitted modifications to existing systems. However, it is essential that the numerical model is accurately verified and validated to provide reliable results. In particular, quantitative methods should be used to pursue an objective assessment of the level of Verification and Validation (VVs reliability.
