一、前言在复合材料的断裂的研究中,纤维断裂产生的应力集中是必须考虑的因素Hedgepeth[1]关于单层复合材料在纤维断裂时的静应力集中和动应力集中系数的计算得到广泛的应用.嵇醒,Hsiao和Chou[2]计算了二层混杂复合材料的动应力集中系数,并讨论了混杂复合材料的混杂效应.Tai[3]的硕士论文计算了三维层内混杂复合材料当纤维断裂时的静应力集中和动应力集中,他的结果关于静应力集中系数较为满意,关于动应力集中系数由于数值计算中作
I. INTRODUCTION In the study of composite fracture, stress concentration caused by fiber fracture is a factor that must be considered. Hedgepeth [1] On the calculation of the static stress concentration and dynamic stress concentration factor of single-layer composite during fiber breakage, The application of X-ray, Hsiao and Chou [2] calculated the dynamic stress concentration factor of two-layer hybrid composites and discussed the hybrid effect of hybrid composites. The master thesis of Tai [3] The static stress concentration and dynamic stress concentration at the time of fiber fracture, his result is more satisfied with the static stress concentration factor, on the dynamic stress concentration factor in the numerical calculation
