摘要: Distributions of the singular (KI, KII) and non-singular (Txx, Tzz) terms along 3D crack front are analyzed for case mixed (mode I II) loading. Relations between singular, specimen thickness calculated in middle plane different values mixity parameter. The parameter varied through 1 (pure mode I), 0.75, 0.5, 0.25–0 pure II. It is shown that increase 8 times influences on KI , KII Tzz . strong effect loading conditions Tzz-stress observed. At same time, there not Txx at conditions.
