A mortar-based cavitation formulation using NURBS-based isogeometric analysis

This paper applies NURBS-based isogeometric analysis to hydrodynamic lubrication problems considering cavitation effects. For this purpose, a mass-conserving cavitation formulation analog to the Augmented Lagrangian method is developed. It describes the complementarity constraints between pressure a...
