Stress triaxiality是什么意思
WebThe stress triaxiality is, besides the strain intensity, the most important factor that controls initiation of ductile fracture. In this study, a series of tests including upsetting tests, shear tests and tensile tests on 2024-T351 aluminum alloy providing clues to fracture ductility for a wide range of stress triaxiality was carried out ... Stress triaxiality has important applications in fracture mechanics and can often be used to predict the type of fracture (i.e. ductile or brittle) within the region defined by that stress state. A higher stress triaxiality corresponds to a stress state which is primarily hydrostatic rather than deviatoric. High stress triaxiality … See more History In 1959 Davies and Connelly introduced so called triaxiality factor, defined as the ratio of Cauchy stress first principal invariant divided by effective stress Davies and Conelly … See more The triaxiality factor $${\displaystyle \eta }$$ gained considerable attention and popularity when Wierzbicki and his collaborators pointed out that not only pressure ( See more Relations $${\displaystyle \eta \,({{\theta }_{sk}})}$$ valid for biaxial (plane) stress states show that in such a case, the values of the triaxiality factor must always remain in the range See more
