- Abstract
- We present the prediction of nonlinear in-plane shear stress strain curves based on complementary strain energy density function. When the [θo] unidirectional laminates are subjected to a combination of shear stresses and axial stresses, the predicted shear responses of laminates are compared with measured experimental data for verifying this accuracy of this model. In this process, the compliance constants are determined to match the measured test results in terms of the influence of on-axis axial stress. Finally, it is shown that the predicted shear stress strain behavior of E-glass/vinylester concurs with experimental curves for all off-axis angles, while shear behavior predictions of boron/epoxy and T800H/3633 laminates agree with experimental results for 30o 45o 60o off-axis angles laminates except 15o off-axis angle laminates. This is because the elastic longitudinal modulus is still significantly higher than the other modulus even for a small off axis angle.
