| Abstract: | The fully plastic J integral of the embedded elliptic crack, on which the uniform pressure is exerted, in the infinite body of power hardening material is derived cleverly by use of energy method in this paper. The fully plastic J integral is a simple analytic form. The solving process is base on the solution of HRR . |
