Cumulative Damage Model for Advanced Composite Materials.

Abstract

Test coupons, taken from laminates of graphite fiber/epoxy structures were developed. Their design allowed for one geometry to be used in tensile and compressive testing at strains of importance in engineering design. The response of four laminates, made up of four different laminate stacking sequences, to quasi-static tension and compression and tension-tension, compression-compression and tension-compression loading was determined. Models for the prediction of strength and life of unnotched laminates under cyclic tensile and compressive loading were developed. (Author, modified-PL).
