To handle the non-linearity of the contact conditions, we apply a primal–dual active set strategy to find the actual contact zone. The algorithm can be easily generalized to multibody contact problems. A suita
Primal–Dual Active SetIn this paper, several active set methods based on classical problems arising in Contact Mechanics are analyzed, namely unilateral/bilateral contact associated with Tresca's/Coulomb's law of friction in small and large deformation. The purpose of this work is to extend an ...

which is the inexact analog of the basic exact primal–dual algorithm presented in [ 15 ]. simply speaking, the main difference to the previous section is that, choosing a type-2 approximation and \(f = 0\) , there are no errors occurring in the input of the proximal operators, such ...
