Progressive failure of a laminate A [0/90]S laminate made of glass/epoxy is subjected to an axial load N x . Use properties of unidirectional glass/epoxy lamina from Table 2.2 and assume that each layer is 0.005 in. thick. a. Use the maximum stress failure theory to find the first and last ply failure of the laminate. b. Draw the stress-strain curve for the laminate till the last ply failure.
