摘要
基于哈密顿原理,通过分离变量及共轭辛本征函数展开法,解析地求解界面裂纹无摩擦接触裂尖的扇形域方程。从另一条途径研究了界面裂尖应力场的特征。
Based on Hamiltonian system, the methods of separation of variables and conjugate symplectric eigenfunction expansion are developed to obtain the stress field at interfacial crack tip with frictionless contact in sectorial domain. A new method is proposed for the research of stress field at interfacial crack tip.
