Abstract: | The bilateral or unilateral contact problem with Coulomb friction between two elastic bodies is considered 1]. An algorithm is introduced to solve the resulting finite element system by a non‐overlapping domain decomposition method 2, 3]. The global problem is transformed to a independant local problems posed in each bodie and a problem posed on the contact surface (the interface problem). The solution is obtained by using a successive approximation method, in each step of this algorithm we solve two intermediate problems the first with prescribed tangential pressure and the second with prescribed normal pressure 8]. Our preconditioner construction is based on the application of the H‐matrix technique 6, 7] together with the representation of the H1/2 seminorm by a sum of partial seminorms 4].
