采用能量法，巧妙地导出了裂纹面上作用着均匀压力、幂硬化材料的无限体内部椭圆裂纹的全塑性Ｊ积分解，该解的形式为简单的解析式，其解法基于ＨＲＲ解［１，２］。
Using the energy method, the all-plastic J-factorization solution of the elliptical crack in an infinitesimal body with uniform pressure and power hardening on the crack surface is ingeniously derived. The solution is in the form of a simple analytic solution based on HRR [1, 2].
