摘要: This paper presents an approach allowing for reduction of a number FE models necessary to be built and analysed in order predict 3D rolling contact fatigue (RCF) crack behaviour. It is done by applying the multi size model. model can used repeatedly estimating effort material near front being under load sizes without changing geometry mesh. In presented approach, this was expressed means histories variation three modes linear elastic fracture mechanics (LEFM) stress intensity factors (SIFs). As example, numerical results obtained with use together test data rail steel were behaviour RCF occurring rails.
