The effect of thickness on components of the non-singular T-stress under mixed mode loading

摘要：

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