Introduced in this paper are two fracture critical surfaces of three dimensional mixed mode obtained from the theoryofstrainenergy density factor and the theoryof maximum tensile strain.
本文对按应变能密度理论和最大拉应变理论所推导出的两个三维复合型断裂临界曲面作了简要介绍。

The thesis recommended the theoryof minimum strainenergy, which says the total structural strain energy can be changed by the increase and decrease of constraint number.
