Abstract
In this paper, the methods using thick shell elements to compute the nonlinear fracture mechanics parameters, the J-and J^^-integrals, are discussed for the through-wall cracked shell problems. To verify the accuracy of the methods, the fracture parameters are calculated for circumferentially through -wall cracked SS 304 piping. The results are shown to have good agreement with the referenced values. Finally, the analysis of crack propagation is performed for circumferentially through-wall cracked SS 304 piping subjected to bending load. Applicability and accuracy are demonstrated by comparing with the experimental results.
