...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...

... . fretting wear third body finite element modeling elastic–plastic contact mechanics stick-slip As shown in Fig. 7 , the linear elastic model of the third body resulted in a stress concentration at the location of wear particles. At this local high contact pressure, the material technically...

... 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...

... test rig was modified with custom mechanical collet grips. Experiments were conducted to investigate the static and fatigue stress life behavior for bearing steels. Additionally, a 3D finite element modeling approach and its applicability as a phenomenological tool for engineering analysis, i.e...

... of the results obtained with finite element models, an experimental test campaign was carried out using a bench capable of measuring seal friction force. Test bench schematics are shown in Fig. 15 . The bench simulates the behavior of a seal mounted on a piston moving inside a cylinder bore. The entire assembly...
