... that are tricky to consider in a numerical solver. Two strategies are discussed in this article. The first one uses a penalty method, while the second one uses a moving mesh method. Their efficiency are compared to reference cases coming from the literature. Then, they are submitted to a transient analysis where...

...A. Ovcharenko; M. Yang; K. Chun; F. E. Talke Contact between a slider and a magnetic recording disk is modeled as transient contact of a sphere on a moving flat. The sphere is assumed to be rigid, and the flat is treated as an elastic-plastic body with isotropic hardening. Heat generation...

...Shangwu Xiong; Chih Lin; Yansong Wang; Wing Kam Liu; Q. Jane Wang A compliance operator is often utilized to evaluate the elastic displacement of surfaces in the simulation of transient and steady-state elastohydrodynamic lubrication of conformal-contact systems. The values of the compliance...

... Elastohydrodynamic Lubrication Film Thickness Nonsteady State Transient Stop-Start Now that steady-state, elastohydrodynamic (EHD) lubrication is reasonably well understood, at least for smooth surfaces, research is beginning to focus on the behavior of EHD systems under nonsteady-state conditions...

...R. P. Glovnea, Research Associate; H. A. Spikes, Professor This paper presents a theoretical model for the behavior of elastohydrodynamic films subjected to transient speed conditions, based on Grubin’s analytical solution for elastohydrodynamic lubrication. This model is applied to predict film...
