Сalculate power and energy parameters of fracture in the field the top of the crack in the shell heat exchanger

Abstract

 It completed a three-dimensional elastic analysis of stress-strain state (SSS) for an elliptic crack located in the cylindrical shell heat exchanger. It was found that for an elliptical crack power and energy parameters of nonlinear fracture vary along the crack front. Qualitative and quantitative ratios for CIN and J-integral on the crack front, given its size and shape of the front.
