摘要
详细分析了弹塑性材料与弹性材料或另一硬化指数ｎ不同的弹塑性材料固结时，界面裂纹尖端场断近展开中一阶项的力学意义，给出由Ｊ积分和应力三轴度Ｑ两个参数共同确定应力和位移分布的条件．
A detailed analysis of the interfacial crack-tip field when an elastoplastic material is bonded to an elastic material or another elastoplastic material with a different hardening exponent n is given in this paper.Themechanical meaning of the first-order term of crack-tip field is pointed out andverified,and the condition under which the distribution of stress and displacement is determined by two parameters(the J-integral as well as the styess triaxiality Q)is discussed.
