木文将Erdogan,Sih的最大周向应力理论及Palaniswamy的能量释放率理论所提出的确定Ⅰ—Ⅱ复合型裂纹断裂角θ_0的解析方程变换成图解方程,进而作出K_1/K_(11)—θ_0和K_(11)/K_1 —θ_0曲线,对复合型裂纹断裂角θ_0的确定提供了一个非常简便的方法。
Mu Wen transformed the analytical equations for determining the I-II complex cracking angle θ_0 proposed by Erdogan, Sih’s maximum circumferential stress theory and Palaniswamy’s energy release rate theory into a graphical equation, and then made K_1/K_(11)-θ_0 The K_(11)/K_1-θ_0 curve provides a very simple method for the determination of the complex crack fracture angle θ_0.
