Abstract

An analytical methodology for prediction of the response of metallic and composite structures subjected to combined intense heating and applied mechanical loading is presented. The proposed methodology includes a thermal analysis which incorporates nonlinear phenomena such as temperature-dependent thermophysical properties, reirradiation losses, and ablation/melting phenomena. A detailed description of a sequential, finite element, ply-by-ply failure analysis based on the maximum stress criterion is given for composite structures as well as a limit analysis approach for metallic structures. Computational projections are substantiated by experimental measurements for an aerospace aluminum alloy and a graphite epoxy plate specimen exposed to simultaneous intense heating and applied tensile loading.
