目前,复合材料在现代技术的各个部门得到了越来越广泛的应用。复合材料有很大的潜力,这不仅是因为它的比力学性能高,而且是因为可根据结构应力状态和作用在结构上的载荷特性,用改变增强纤维排列的方法得到合乎需要的材料。复合材料的力学问题,不仅很重要而且很复杂。复合材料理论不仅对确定结构的应力-应变状态,而且对 At present, composites have been more and more widely used in various departments of modern technology. Composites have great potential not only because of their high specific mechanical properties but also because of the ability to change the orientation of the reinforcing fibers to the desired material based on the structural stress state and the structural loading behavior. The mechanics of composite materials is not only very important but also complex. Composites theory not only determines the structure’s stress-strain state, but also
