Webif the surfaces of constant stellar density are triaxial ellipsoids with axial ratios varying with radius, as illustrated in Fig. 3.2. Thus isophotal twists are generally interpreted as evidence for triaxiality (Kormendy 1982). 3.3.1 Non-elliptical isophotes High signal-to-noiseCCD images of elliptical galaxiesshow that manyhave non ... 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 $${\displaystyle {{\eta }_{DC}}\equiv 3\,{{\sigma }_{m}}/{{\sigma }_{ef}}={{I}_{1}}/{\sqrt {3{{J}_{2}}}}}$$, cf. formula (35) in Davies and … See more The triaxiality factor $${\displaystyle \eta }$$ gained considerable attention and popularity when Wierzbicki and his collaborators pointed out that not only pressure ($${\displaystyle -{{\sigma }_{m}}}$$) … 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 Stress triaxiality has important applications in fracture mechanics and can often be used to predict the type of fracture (i.e. ductile … See more
