摘要: 复合材料纵横剪切应力存在明显的非线性行为,本文针对碳纤维和玻璃纤维编织复合材料的剪切非线性现象,展开了试验和数值仿真研究。采用类似塑性损伤的本构方程描述了复合材料剪切非线性本构,考虑了塑性应变对残余变形的影响。通过与试验结果对比发现,本文模型可以准确描述编织复合材料的载荷-位移曲线、损伤分布和失效形貌,验证了本文模型的准确性。

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
