In dynamic material experiments where metal surfaces receive an extreme shock loading, it is often of interest to understand the size distribution of particles ejected from its surface. Mie scattering theory, a closed-form solution to Maxwell’s equations under assumptions such as spherical particles, suggests we can determine the ejecta size distribution by relating it to measured laser light scattered off the particles and collected at different angles.

This presentation summarizes the development and implementation of quantitative design criteria motivated by targeted inference objectives for identifying new, potentially expensive computational or physical experiments. The first application is concerned with estimating features of quantities of interest arising from complex computational models, such as quantiles or failure probabilities. A sequential strategy is proposed for iterative refinement of the importance distributons used to efficiently sample the uncertain inputs to the computational model.
