Abstract: The determination of the elastoplastic deformation regime arising at the microcontact of a deformable ellipsoid and a rigid smooth flat was the main purpose of this study. One-eighth of an ...

Abstract: A new method is developed in the present study to determine the elastoplastic regime of a spherical asperity in terms of the interference of two contact surfaces. This method provides an ...

Abstract: In the present study, the formulas for the asperity contact loads (Fec and Fpc) corresponding to the critical interferences at the inception of elastoplastic and fully plastic deformations are ...

Abstract: Low-velocity water flow in oceans and rivers contains abundant energy that can be harnessed. In this article, energy from low-velocity flow is converted into the vibration of an underwater tube, which is elastically supported ...
