interfacial failure meaning in English

界面断裂

A finite element analysis ( fea ) was eventually conducted , using mori - tanaka model and j - integral , to further explain the toughening mechanisms and fracture behaviour of the particle interleaved composites . the aim of the analysis was to examine the influence of the particle concentration and size , and the interaction between the particle and the crack tip . fea results indicate that interlayer zones can effectively lower j - integral and stress around the crack tip , and the high stress distribution in the region close to the interface can be the driving force for interfacial failure
本文的最后还借助于有限元方法对层间增韧复合材料进行了宏观和细观断裂韧性分析，基于mori - tanaka等效夹杂理论，计算了颗粒含量和尺寸对j积分的影响，有限元分析的结果同样表明层间增韧可以有效的降低裂纹尖端应力水平，并暗示界面是可能存在的失效原因，所进行的数值分析起到了进一步支持和解释增韧机理的作用。
