Paper Title:
A Proposed Thickness Distribution of Elbow Resisting Ratcheting
  Abstract

With the analysis of thickness distributions of elbow by the equal-strength criterion and plastic deformation by pushing bending process, an ideal thickness distribution is proposed with the consideration of elbow processing characteristics to improve its ratcheting resistance. Ratcheting of elbows under internal pressure and reversed in-plane bending is analyzed with Chaboche model by finite element method, which shows that elbows with the proposed thickness distribution have great resistance to ratcheting compared with equal thickness elbows.
