采用有限元法，建立了有关的单胞模型和相关的边界条件。并着重研究了复合材料的几何结构参数与单向不连续碳纤维增强热塑性树脂复合材料的细观弹塑性应力应变的关系，分析了纤维重叠比、纤维端部的不连续性对复合材料弹性模量和应力集中系数的影响。
Using the finite element method, the related cell model and the related boundary conditions are established. The relationship between the geometrical parameters of composite materials and the mesoscopic elastic-plastic stress-strain of unidirectional continuous carbon fiber reinforced thermoplastic resin composites was studied. The effects of fiber overlap ratio, discontinuity of fiber ends on the elastic modulus And stress concentration factor.
