In loading process of FRP laminates, two kinds of nonlinearity are observed. One of them is concerned with damage, the other is not. The nonlinearity unrelated with damage is mostly due to the nonlinear property of lamina in shear. On the other hand, the nonlinearity related with damage is caused by matrix cracking evolution in each ply. In the previous works, we presented the theory for predicting a laminate stress-strain response in damage process on the basis of continuum damage mechanics. This paper extends the theory to include the damage unrelated nonlinearity using Hahn & Tsai nonlinear elasticity theory. Comparisons are made between the analytical predictions and the experimental results. The analytical method formulated in this paper can be used for general composite laminates under the plane stress condition.
