Abstract
Strain energy release rate associated with matrix cracking in the θ- layer of unbalanced symmetric [0/θ], composite laminate is predicted analytically using a 2-D shear lag stress analysis and the Equivalent Constraint Model (ECM). Its dependence on the crack density and ply orientation angle is examined for glass/epoxy and carbon/epoxy laminates. Suitability of a mixed mode fracture criterion to predict the cracking onset strain is discussed.
