This paper presents an algorithm to solve mechanical contact problems between two bodies or more, for linear elastic and finite deformation problems. The contact problem is considered as a minimization problem of an energy. The interior point method is used to solve the minimization problem. This algorithm is symmetric and the user no longer needs to specify a slave body and a master one. The algorithm was developed using FreeFEM and IPOPT software.
