Modeling non-through surface cracks in the thin-walled structures

Abstract


Describes the program developed macros for the automatic modeling of the FEM-package ANSYS threedimensional surface cracks in thin-walled structures and calculate the parameters of fracture mechanics along the curved semi-elliptical crack front. In order to determine the values of J-integral method of integrating the region. We give a numerical example of modeling the outer surface cracks in the pipe and the results of calculating the parameters of fracture mechanics.
