Abstract
The stress intensity factors (SIFs) for multiple rolling contact fatigue cracks of a network in the Iran railway under vehicle dynamic load are evaluated in this paper. Stress intensity factors evaluation under dynamic loading is simulated in three-dimensional using linear elastic boundary element code. For this purpose, an UIC60 rail with accurate geometry using boundary element method is studied. In this regard, at first a three-dimensional model in Franc3D is provided. Finally, the influences of the friction coefficient between the wheel and rail, crack surface friction, trapped fluid and initial crack length on SIFs are investigated in detail.
