Abstract
We use structural dynamics models implemented in codes to predict the shock response spectra (SRS) at a specific location for two bodies connected with a joint excited by an external force. The Iwan model is used to represent the energy dissipation of the joint between the two bodies. For this problem, experimental data has been collected and processed to provide shock response spectra at the corresponding location. This work provides a model validation assessment for the SRS at various frequencies using techniques that are based on a multivariate metric that accounts for correlated errors in differences between prediction and measurement. In this paper, we describe the problem, provide results of the simulation and experiment, describe the validation assessment technique, and present results for the validation assessment.
