Simulation of the Crack Propagation through a Planar Plate with the Middle Positioned Cylindrical Hole

Abstract

A prediction of crack propagation is subject of research of many scientists. Understanding crack occurrence and propagation could save lives (i.e. in airplane industry), or at least reduce the costs occurred by unexpected failures and stoppages. In this paper it is provided a brief theoretical background of the crack propagation regarding to stress intensity factor, and simulation of crack propagation through a planar plate made of steel with the middle positioned cylindrical hole, by means of Abaqus software. In addition, it is performed calculation of stress intensity factors with MORFEO, software that could be implemented onto Abaqus.
