Nominally static contacts such as bolted or shrink-fit joints typically experience regions of microslip when subjected to oscillatory loading. This results in energy dissipation, reflected as apparent hysteretic damping of the system, and also may cause the initiation of fretting fatigue cracks. Early theoretical studies of the Hertzian contact problem by Cattaneo and Mindlin were confirmed exp...

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...

In this paper, accumulation of plastic deformation of AISI 1045 steel plates with circular cutouts under cyclic axial loading is studied. Loading was applied under force-control conditions. Experimental tests were performed using a Zwick/Roell servo hydraulic machine. Under force-control loading with nonzero mean force, plastic strain was accumulated in continuous cycles called ratcheting. Nume...

A B S T R A C T Recently, various methods have been proposed to assess the risk of rolling contact fatigue failure by Ekberg, Kabo and Andersson, and in particular, the Dang Van multiaxial fatigue criterion has been suggested in a simple approximate formulation. In this note, it is found that the approximation implied can be very significant; the calculation is improved and corrected, and focus...

The purpose of this paper is to present a method for calculating the upper bound limit loads plate bending using conforming Hsieh-Clough-Tocher (HCT) element. These can be obtained from Koiter’s kinematic shakedown theorem case one load vertex instead theorem. When combining with approximated displacement field, analysis turns into an optimization problem and effectively solved by Second-Order ...
