Abstract

This paper provides a comparison of the J-integral estimation method under combined primary and secondary stress in the R6, RCC-MR A16 code. The comparisons of each code are based on finite element analysis using ABAQUS with regard to the crack shape, crack depth, and magnitude of secondary load. The estimate of the R6 code is conservative near Lr = 1, and that of the RCC-MR A16 code is conservative near Lr = 0. As a result, this paper proposes a modified method of J-integral estimation in the R6, RCC-MR A16 code. The J-integral using the modified method corresponds to the finite element analysis result.
