3-Dimensional Response of Composites

Abstract

This report contains analytical models developed for the prediction of three-dimensional response of composites. Two aspects of the problem of stress and failure analysis are considered. One pertains to a macromechanical model which the development of a global-local finite element method for stress analysis of composite laminates is given. The other aspect incorporates a micromechanics approach leading to a model, termed NDSANDS, for the stress and failure analysis of carbon-carbon composites. Again, the global-local formulation for the laminate stress analysis is numerically solved by two different finite element techniques. The NDSANDS model incorporates the effects of processing by evaluating the residual stresses due to hygrothermal effects. A number of problems has been solved for illustrating the effectiveness of all the above mentioned models, It is believed that these models are of extreme importance in studying the optimum design parameters in structural composites.
