摘要
利用微分积分方程方法研究三维无限弹性体内嵌平片裂纹问题．研究表明，如果作用在裂纹面上的载荷是幂函数形式，则其位移间断值有闭合形式解．本文得出了裂纹面上作用高次幂法向载荷的多种情形的应力强度因子．
Stress intensity factors of an embedded elliptical crack in threedimensional elastomer are studied in this paper by using differentialintegral equtions. It is found that if the tractions applied on the crack face takes the form of power function xp0yq0,the displacement jump can be evaluated in a closed form,and stres intensity factors can be found immediately.
