J-Integral Estimate for Circumferential Cracked Pipes Under Primary and Secondary Stress in R, RBC-MR A

  • 1. Korea Univ., Seoul (Korea, Republic of)

Description

This paper provides a comparison of the J-integral estimation method under combined primary and secondary stress in the R, RBC-MR A code. The comparisons of each code are based on finite element analysis using Abacus with regard to the crack shape, crack depth, and magnitude of secondary load. The estimate of the R code is conservative near Lr = 1, and that of the RBC-MR A code is conservative near Lr = 0. As a result, this paper proposes a modified method of J-integral estimation in the R, RCCMR A code. The J-integral using the modified method corresponds to the finite element analysis result
