    Scalable TFETI algorithm for two dimensional multibody contact problems with friction

  • Original language description

    Total FETI (TFETI) based domain decomposition algorithm with preconditioning by a natural coarse grid of rigid body motions is adapted to the solution of two-dimensional multibody contact problems of elasticity with the Coulomb friction and proved to bescalable for the Tresca friction. The algorithm finds an approximate solution at the cost asymptotically proportional to the number of variables provided the ratio of the decomposition parameter and the discretization parameter is bounded A Total FETI (TFETI) based domain decomposition algorithm with preconditioning by a natural coarse grid of the rigid body motions is adapted to the solution of two dimensional multibody contact problems of elasticity with Coulomb friction and proved to be scalable forTresca friction.
