โœฆ Synopsis

A numerical procedure is presented for predicting failure in laminated composites subjected to simultaneous intense localized heating and applied mechanical loads. The method consists of a non-linear two-dimensional, axisymmetric finite difference thermal analyser which considers the effects of surface ablation, radiation and convection losses and temperature dependent thermophysical properties. The thermal results are used in conjunction with a flat plate finite element code to predict the failure of laminated composites. Predictions based on the numerical analyses are compared with experimental results obtained from mechanically loaded graphite epoxy coupons spot-irradiated at various intensities.

This paper is concerned with the experimental and numerical study of stiffened laminated composite plates exposed to a normal blast shock wave. For this purpose a detonation is developed from the reaction of LPG-O 2 mixtures in a long circular cylindrical shock tube. The detonation wave goes through

## Abstract This paper focuses on the nonโ€linear responses in thin cylindrical structures subjected to combined mechanical and thermal loads. The coupling effects of mechanical deformation and temperature in the material are considered through the development of a thermoโ€elastoโ€viscoplastic constit
