Showing papers on "Laplace pressure published in 1993"
TL;DR: In this paper, the generalized Laplace equation was used to estimate the level of stress arising from the interaction of surface active melt with metal, and the solution of the corresponding problem for a system "elastic solid-elastic surface" was obtained.
Abstract: From the analysis of the mechanical equilibrium of an interface between two different media (the generalized Laplace equation) it follows that, in addition to the discontinuity of the normal stress, there exists a discontinuity of the tangential stress across this interface due to the surface tension gradient. Using the solution of the corresponding problem for a system “elastic solid-elastic surface” the generalization of the Cassie equation for the contact angle on the heterogeneous surface is obtained and the level of stress arising from the interaction of surface-active melt with metal is estimated.
