Original Abstract

Fatigue cracks are found during the regular structural inspections. To precisely describe/suggest of fatigue cracks propagation throughout structure and for designed service life, the knowledge of calibration functions is important. The cracks usually propagate from the edge or the surface of the structural element. The theoretical model of fatigue crack propagation is based on linear fracture mechanics (Paris law). Steel structural elements are subjected to various bending load (three- and four-point bending, pure bending etc.). The calibration functions for the edge cracks are calculated for various load and appropriate polynomial function independent on the distance are proposed for 3PB and 4PB load.

Keywords

Fracture mechanics, calibration curve, stress intensity factor, Paris-Erdogan Law, edge crack.
