用法和例句

The crack tip fields and out-of-plane stress constraint of the specimens were analyzed using three dimensional elastic-plastic theory.

以三维弹塑性断裂理论为基础,对有限厚度板裂纹端部应力场、三维应力约束进行了分析,通过对不同厚度、不同初始裂纹长度在不同温度下三点弯曲试件的断裂韧性测试断口观测和理论分析获得如下结果:离面约束对裂尖应力场及断裂韧性有强烈的影响;断口均产生分层裂纹,其位置、大小和数量与试样厚度、温度和裂纹初始长度有关;温度较低时,分层裂纹距主裂纹根部一定距离,分层裂纹宽度较小,对厚度效应影响较小;温度较高时,分层裂纹首先出现在主裂纹根部,分层裂纹宽度较大且充分张开,降低了试样的有效厚度。
