摘要
采用剪滞理论，研究了三纵向拉伸的层间混杂复合材料由某些低延伸层已发生破坏和高延伸层中部分纤维断裂相互作用而导致的应力重分布．在此基础上，采用随机临界核理论，对层间混杂叠层复合材料的最终拉伸破坏进行细观统计分析．结果表明，估计的最终拉伸破坏应变与现有的实验有较好的符合．
Using the shear-lag theory, this paper studies the stress redistributions induced by the interaction of both failure of low elongation layers and breakage of some fibers in high elongation layers in interply hybrid composites. On the basis of these,a micro statistical analysis of the ultimate tensile failure of interply hybrids is performed by using the random critical-core theory. Calculating results show that the predictions of ultimate tensile failure strain coincide relatively well with the existing experiments.
