摘要：

Nonlinear mechanical behavior of carbon/epoxy unidirectional and angle-ply laminates under uniaxial tensile loading is investigated experimentally. The generalized method of cells is applied to predict the nonlinear stress-strain relation of the unidirectional laminates under off-axis tensile loading. The one-parameter plasticity model is also used to characterize the nonlinear behavior of the unidirectional laminates. The mechanical behavior of the angle-ply laminates is predicted by using the one-parameter plasticity model of the unidirectional laminates.
