... that the borehole wall should be considered as a non-ideal semi-permeable medium. When the wellbore is exposed to the drilling fluid, the dynamic modification of pore pressure on the borehole surface is required to account for fluid entering the formation. In this paper, we present an analytical solution for a semi...

Hertzian contact mechanics can be used to model such contacts, but since there is no closed-form analytical solution to predict the major and minor axes of the contact zone ellipse, approximate numerical methods have been developed, some of which are very accurate. Predictions of the mutual approach...
