The paper refers to the influence of corrosion on installation and development thermos - mechanical contact fatigue metallic elements. analysis takes into account thermal Jacq effect position origin a crack following fatigue. Here are presents some aspects concerning wear links these two kinds in common deterioration layer. Schematic draw test stand is presented with main component elements ano...

The objective of this investigation is to evaluate the cyclic plastic deformation response at subsurface during rolling contact fatigue (RCF) under conditions pure and rolling-sliding. finite element simulation results indicate that slip-to-roll ratio (SRR)has an immense effect on evolution RCF. At SRR 0% (pure rolling), symmetric shear stress cycling evident subsurface, as a result shakedown t...

a plain strain analysis of frictional rolling contact on an elastic graded coating is presented in this paper. finite element method is applied to gain an understanding of the stresses and contact zone properties caused during rolling contact. the effects of friction, material stiffness ratio and coating thickness on stresses in contact zone and coating/substrate interface are studied. shear mo...

A new multiaxial high-cycle fatigue initiation life prediction model for railroad wheels is proposed in this paper. A general fatigue damage analysis methodology for complex mechanical components is developed and applied to the wheel/rail rolling contact fatigue problem. A 3-D elasto-plastic finite element model is used for stress analysis. A submodeling technique is used to achieve both comput...
