| 摘 要： | 提出一个新的、由光弹性与权函数两种方法相结合确定应力强度因子的混合法．用此方法求解了单圆孔有限宽板孔边单侧有一水平裂纹、双圆孔无限宽板中心有一水平裂纹受均匀拉伸和具有单边垂直裂纹的半圆形板受三点弯曲时的应力强度因子，并与文献作了比较，两者符合良好，为断裂力学的研究和工程应用提供了一个经济有效的方法．

| Abstract: | A new mixing method-the photoelasticity in combination with the weight function method is provided. The stress intensity factors for finite plates with single hole-edge crack, for a center crack approaching two holes in an infinite plate and for semi-circular specimens under three-point bending are evaluated effectively and economically by using the new mixing method.Compared with the references, the results agree well with the reference obtained. This paper provides effective means for studying fracture mechanics and engineering application. |
