J Integral Computation for Cracks in Polypropylene Pipes under Internal Pressure

Abstract:

In the present work, the three-dimensional finite element method is used to analyze the propagation criteria for a semi-elliptical crack in a polypropylene pipe under internal pressure. The crack propagation behavior is analyzed by J-integral calculation. The effects of the crack position in the pipe and the loading, as well as the size and configuration of the crack, are examined. The results obtained enable us to deduce that the propagation of a crack depends on several factors.
