چکیده انگلیسی
A new pressure-dependent elasto-plastic constitutive model for polymer based composite laminates with unidirectional plies is established and implemented into finite element software to simulate off-axis loading tests of two kinds of composites. The validity of the new plasticity model is proved by available off-axis loading test results. Additionally, accuracies and efficiencies of the backward Euler algorithm and the forward Euler algorithm respective in solving plastic deformation of fiber-reinforced composite materials are analyzed. Compared with the forward Euler algorithm based plasticity model, the backward Euler scheme shows comparative prediction accuracy of laminate plastic behavior and better computational efficiency. This paper is expected to facilitate the numerical predictions of composite laminates' elasto-plastic behaviors for researchers and engineers.
