The Calculation of the Crack Tip Stress Intensity Factor Sections

摘要: 本文应用分区广义变分原理,提出了求解含有裂纹的型材应力强度因子的计算方法。并对角材中含有边缘裂纹和槽形型材中含有中心裂纹的应力强度因子进行了数值计算,计算结果绘成了曲线。

Abstract: A calculation method is proposed to determine the crack tip stress intensity factors for sections on the basis of zonal generalized variational principles⁸. Several numerical example are given of angles and channels.
