Analyses of Nonlinear Fracture Mechanics Parameters of Through-Wall Cracked Piping
A new evaluation method using thick shell element is proposed to calculate the distribution of nonlinear fracture mechanics parameters, such as path independent integral J and Ĵ, along crack fronts of throug-wall cracks in plate and shell structures. Some results of the Ĵ-integral analyses are presented to show the effectiveness of the present evaluation method.
