J. Krishnasamy et Mj. Jakiela, A METHOD TO RESOLVE AMBIGUITIES IN CORNER-CORNER INTERACTIONS BETWEENPOLYGONS IN THE CONTEXT OF MOTION SIMULATIONS, Engineering computations, 12(2), 1995, pp. 135-144
The motion of systems of polygonal objects is characterized by discont
inuities due to changes in the set of contacts between polygons. Effec
tive simulations of such a motion requires a simulation scheme that ca
n automatically update the set of contacts during the simulation. This
article focuses on a contact updating problem that arises when a pena
lty based contact model is used. A penalty based model requires a fini
te overlap of contacting polygons. This overlap results in ambiguities
in characterizing corner-corner contact between polygons. A simple ye
t effective scheme to overcome such ambiguities is presented.
