Abstract: Composite materials exhibit significant nonlinear behavior in longitudinal and transverse shear stress. The experimental and numerical simulation studies on the shear nonlinear phenomenon of carbon fiber and glass fiber woven composite materials are conducted in this paper. A constitutive equation similar to plastic damage is used to describe the shear nonlinear constitutive behavior of composite materials, taking into account the influence of plastic strain on residual deformation. By comparing with the experimental results, it is found that the model in this paper can accurately describe the load displacement curve, damage distribution, and failure morphology of woven composite materials, verifying the accuracy of the proposed model.

Key words: composite materials, shear nonlinearity, numerical simulation, residual deformation
