A Study on the Fatigue Test in A5052 Alloy Sheet Under Mixed Mode Loading

혼합모드 하중하의 A5052 합금판재에서의 피로시험에 관한 연구

  • Published : 2002.05.01


In this paper, for the mixed mode fatigue problem, the method of determining testing load was proposed. It is based on the plastic zone size and the limited maximum stress intensity factor by ASTM STANDARD E 647-00. The application method of maximum tangential stress criterion and the stress intensity factor for the finite width specimen was proposed. In the result of applying the method to mixed mode fat gut test for A5052 H34, it obtained the satisfactory experimental results on the stable crack growth.
