Abstract: A mathematical programming solution based on finite element method is used to analyze wall slip of viscoplastic lubrication in a metal-rolling inlet zone. Slip velocity can be directly obtained ...

Abstract: Recently, microneedles (or microneedle arrays) for transdermal drug delivery have received increasing attention because they can provide painless, minimal invasiveness and time-released drug delivery. ...

Abstract: An effective mathematical method to deal with the viscoplastic lubrication model is presented here by applying the parametric variational principle (Zhong, 1985). The plastic slippage of lubricant ...

Abstract: The classical Reynolds theory reveals that a converging gap is the first necessary condition to generate a hydrodynamic pressure in a viscous fluid film confined between two solid surfaces with ...

Abstract: The volume of lubrication literature continued to expand, reflecting the increased experimental and theoretical attention being focused upon this discipline. Special attention is devoted to seals ...
