PREDICTION OF INTERLAMINAR STRESSES ACTING IN THE ANGLE PLY E-GLASS EPOXY COMPOSITES USING ANALYTICAL AND NUMERICAL METHODS

Abstract

Prediction of interlaminar stress is the leading research area in the field of composite structures nowadays. Many research works related to the interlaminar stresses induced in the composite structures, such as the formulation of analytical solutions to predict the interlaminar stresses, finding out the additional provision to be made in the experimental set-up for the measurement of interlaminar stress, and the development of various theories for the accurate determination of inter-laminar stresses and free edge stresses are going on. Among the research works carried out so far, cross-ply composites have been concentrated more because of their more application areas. The present work considers an angle ply E-Glass epoxy composite structure for the interlaminar stress analysis. Interlaminar stresses induced in the considered angle ply composite for the given loading condition have been predicted using analytical and numerical analyses, and the results have been compared.
