S. Abdullah et Dt. Gethin, SIMULATION OF SURFACE-TENSION EFFECT DURING FILLING OF A THIN-SECTIONCAVITY VIA AN INTERFACE ELEMENT, Communications in numerical methods in engineering, 14(3), 1998, pp. 229-240
An interface element to model the pressure discontinuity due to surfac
e tension when applied to the filling of a thin section cavity is pres
ented. The equations used to form the element matrix for the interface
element are the line integral form of the continuity and momentum equ
ations. During the development of the finite element model, the pressu
re difference across the free surface due to surface tension is treate
d as an additional traction and is applied to all element sides which
form the free surface. Simple numerical examples are then presented to
illustrate the technique on the filling of a rectangular thin section
cavity. (C) 1998 John Wiley & Sons, Ltd.
