STIFNESS AND STRENGTH OF ELASTIC MATRIX WITH MISORIENTED MICROCRACKS AND PROLATE SPHEROIDS
-
摘要: 针对含随机分布微裂纹及椭球颗粒的复合材料，通过考虑椭球颗粒内的本征应变及其与微裂纹的相互作用，利用等效夹杂方法研究了微裂纹损伤对材料有效模量和强度的影响，推导了复合材料的细观应力场及本构关系，并导出了材料破坏的临界条件．Abstract: In This paper,a new andytical model is used to study the influence of misorientedmicrocracks on stiffness and strength of prolate spe roid-rei nforced composite material witheighst rain. The interaction b etween microcracks and prolate spheroids is analysed usingequlvalent inclusion method and the stress field, constitutive relation and the critical failurecondition are given.
