SUMMARY:
For a sandwich plate system consisting of steel faceplates and a fully bonded core made from polyurethane (so-called SPS plates), material and failure models have been developed. These are an elastic-plastic material model for the core, a criterion that predicts fracture of the core and a failure model to predict delamination between core and faceplates. Examples are given on how to use these models for FE analysis of sandwich structures subjected to extreme loads.
