摘要
采用边界元法分析两相异质材料切口尖端的应力场,再采用后处理的方法计算切口的应力强度因子。通过对界面裂纹这一特例进行分析,并和参考解对照,证明文中方法的有效性。最后,分析了弹性模量比、切口开角、切口深度等因素对切口应力强度因子的影响规律。
The boundary element method is introduced to study the stress field near the bi material V notch.The post process method is used to calculate the stress intensity factors of the bi material V notch.The stress intensity factors of the interfacial crack are evaluated and compared with the reference ones to verify the effectiveness of the present method.At last,the influence of the elasticity modulus ratio,the opening angle and the depth of the V notch on the stress intensity factors are respectively investigated by the present method.
