Abstract: Considering the actual roughness dimensions as well as the typical dimensions of a hydrodynamically lubricating film, the Stokes equations are used to analyze the roughness effects. The surface ...

Abstract: This paper studies the effects of some modeling parameters on the accuracy of finite element simulation in sheet-metal forming. A simple stepdie, which simulates binder forming, is used. In ...

Abstract: The existence and consequence of hydrodynamic lubrication in sheet metal forming is demonstrated using a model problem of hemispherical punch stretch forming. The problem is solved by incorporating ...
