SUCHA
Force distributed on a surface
Description
This element applies a normal pressure $P$ and two tangent stresses $\tau$ oriented along axes $\xi$ and $\eta$ on a surface defined by a variable number of nodes (3, 4, 6 or 8).
The forces are defined by the fictive law LICHA. These forces are multiplicated either by multiplicator FMULT or by DMULT.
The positive axis of tangent stresses is directed in the opposite direction of axes $\xi$ (oriented positively from IP1 to IP2) and $\eta$ (oriented positively from IP1 to IP3). The positive axis for pressure is also opposite to the normal of the element.
Type: 19
Implemented by: J-P. Radu - November 1988
