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