摘要:
利用双区域边界元法计算界面裂缝缝端应力场,用缝端应力强度因子KⅠ与应力的关系式求得KⅠ-γ曲线(r为极坐标),从而求得r=0处的应力强度因子.算例表明,边界元法是计算界面裂缝的有效方法.
Abstract:
The two-region boundary element method is used to calculate the stress field at the end of the interface fracture, and the relationship between the stress intensity factor KI. and the stress is obtained by the relationship between the stress intensity factor KI γ. and the stress (r is the polar coordinate), so as to obtain the stress intensity factor at r=0. Examples show that the boundary element method is an effective method for calculating interfacial cracks.
