Quartic formulation of Coulomb 3D frictional contact
Abstract
In this paper, we focus on the problem of a single contact with Coulomb friction, which we reduce to a root-nding problem on a degree 4 polynomial. This formulation give us the exact number of solutions, as well as their analytical form when they exist.
Dans ce document, nous reformulons le problème unitaire (1 con- tact frottant) en la recherche de zéro d'un polynôme du quatrième degré. Si elles existent, cette formulation donne la forme analytique des solutions.
