| 摘 要： | 本文提出用以确定就力强度因子的一个新的由光弹性与权函数两种方法相结合的混合法，用此方法经济有效地求解了含单边裂纹半圆形板受三点及四点弯曲时的应力强度因子，并与和了比较，二者符合良好。同时还分别给出了应力强度因子随载荷位置和裂纹长度变化的情况。本方法为断裂力学的研究和工程应用提供了一个有效的手段。

| Abstract: | In this paper, a new mixing method-the photoelasticity in combination with the weight function methoel was provided. The stress intensity factors for semi - circular specimens under three - point and four - point are evaluated effectively and economically by using the new mixing method.Compared with the reference5]. the result answers that reference5]obtained . The Variation due to the crack length and load support is considered - This paper provided effective means for studying on fracture mechanics and engineering application. |
