FAILURE RESISTANCE IN TITANIUM-ALLOY JOINTS UNDER BIAXIAL LOADING WITH TENSION

摘要

On the basis of the criteria of the linear and non-linear distruction mechanics new quantitative characteristics of changing the parameters of ciclic distruction resistance depending upon the relationship of biaxial nominal stresses, crack inclination angle and tension in the joint were obtained. On the basis of the numerical analysis of the "cross" - type specimen having a central hole into which a pin with preload was adjusted imitating the insertion of a bolt into a smooth hole, the machanisms of the influence of loading conditions on the coefficients of intensities of the stresses were obtained.
