“…The above is substantiated by the data (Figs. 2 and 3) similar to these for nonuniform biaxial loading [8], where N is the number of loading cycles at each step preceding full specimen unloading and shifting to the next loading step of a higher stress level, without specimen fracture, N b is the number of loading cycles to specimen fracture, s i , ¢ s i max , and s i max are the maximum stress intensities at an examined loading step with loading termination without specimen fracture, and after equilibrium attainment of the specimen's metal, respectively, and s ib is the stress intensity corresponding to specimen fracture under single loading. Homogeneity Factor Variations with a Stress State.…”
