一前言随着复合材料日益广泛的应用,研究带缺陷复合材料的剩余强度问题已越来越迫切。迄今为止,大量的试验研究表明复合材料的破坏机理与金属完全不同,除了它们自身的各向异性特性外,更主要的是随着载荷的增加,这一损伤区也不断扩展直至破坏。因此,带缺陷复合材料的强度问题实际上可以归结为损伤区的产生、扩展和失稳问 I. INTRODUCTION With the increasingly widespread application of composites, the research on the residual strength of composites with defects has become more and more urgent. So far, a large number of experimental studies have shown that the failure mechanism of composites is completely different from that of metals. In addition to their own anisotropic properties, more importantly, as the load increases, the damaged region also expands to destruction. Therefore, the strength of the composites with defects can be attributed to the production, propagation and failure of the damaged area
