Validation Metrics for Response Histories: A Review with Case Studies 2006-01-0458

The comparison of transient response results can be quantified using metrics which represent the magnitude and phase of the wave forms. Such quantified comparisons are useful to analysts as they seek to improve numerical models and need a measure of the degree of change due to the improvement. More importantly, the use of such metrics in validation assessments, i.e. comparisons of measured and computed wave forms, is a highly recommend as part of an overall verification & validation effort. Two recently developed metrics are presented, and their effectiveness is demonstrated through assessments of analytical wave forms, free-field velocity and stress measurements, and comparison with Subject Matter Expert opinion.
