摘要	By combining the classical strength theory with the modern damage mechanics, a new annotation of generalized yield of high strength steel in stress triaxiality space was presented. On the basis of identity of yield and brittle fracture of high strength steel in triaxial symmetrical stress field, this paper deduced crack criterion in stress trixiality space. By comparing the results of numerical simulations and fracture experiments of notched bars, the effectiveness and accuracy of the crack criterion were verified. A mechanical explanation of the generalized yield and crack model of high strength steel was made. The generalized yield and crack model was an attempt to solve high strength steel fracture of crack and uncrack body.
