摘要
通过有限元计算,得到薄板两侧半圆形切口及其附近的应力分布情况,并分析了这些地方的应力集中系数。并将计算结果与实验研究得到的应力集中系数进行了比较。结果表明,有限元方法可以直接而有效地模拟应力集中情况。
The stress distribution of double edge semi-circles notches which are in the plate and region of them is studied by finite element method, and factors of stress concentration of these places are analyzed. The calculation result is compared with factors of stress concentration got by experiment. It＇s shown that the finite element method can simulate the stress concentration effectively and accurately.
