...Arman Ahmadi; Farshid Sadeghi In this investigation, a three-dimensional (3D) finite element model (FEM) was developed to study fretting wear of Hertzian circular and line contacts. The wear law incorporated in this model is based on the accumulated dissipated energy (ADE). A stress-based damage...

... body finite element modeling elastic–plastic contact mechanics stick-slip Fretting wear occurs when two bodies in contact are subject to small oscillatory displacements. This wear phenomenon is common in many industrial applications, such as gears, couplings, bearings, screws, valves...

... their equivalent sum surface and a rigid plane. In this work, we develop detailed finite element models to test the sum surface assumption for surfaces with Gaussian and exponential autocorrelation functions. We consider surfaces with differing surface roughness and correlation length values. For each case, we...

...) results. Evaluation of the fatigue specimens in the high cycle regime indicates shear driven crack initiation followed by normal stress driven propagation, resulting in a helical crack pattern. A 3D finite element model was then developed to investigate fatigue damage in torsion specimen and replicate...
