Abstract

This paper presents a novel formulation of the completed indirect boundary element method to study the deformation of a slow viscous flow in a bounded region subject to surface tension effects. The pro- posed formulation leads to a Fredholm integral equation of the second kind in terms of only one surface potential for which uniqueness of solution is always guaranteed. 1 Introduction Sintering is a process in which a granular compact of metals, ionic crystals or glasses, consisting of many particles, is heated to such a high temperature that the mobility of the material is suf
