Abstract
   In this paper, using the Abaqus finite element software, the torsional hysteresis of X52, X60, X65 steels under loadings with different torsion values, has been numerically investigated and they are compared to each other. The shear stress, effective stress, residual stress and elastic and plastic ...  Read More

Assessment of the Existing Models to Estimate the Fatigue Life under both Multiaxial in Phase and 90° Out of Phase Loading Conditions

Rahmatollah Ghajar; G. R. Rashed

Volume 4, Issue 3 , September 2007, , Pages 25-35

Abstract
  Engineers have a range of methods to estimate the fatigue life under multiaxial conditions. Each of these predictive methods is generally subjected to restrictions, related to the inherent simplified assumptions. The objective of this paper is to evaluate the validity of commonly used multiaxial fatigue ...  Read More
