Fixed point strategies for elastostatic frictional contact problems
نویسندگان
چکیده
Analysis and theoretical comparison between several fixed point strategies and Uzawa algorithms (for classical and augmented Lagrangian) are performed to solve the so called Signorini problem with Coulomb friction without any regularization. Thanks to a formalism coming from convex analysis, some new fixed point strategies are presented and compared to already known methods. The analysis is first performed on continuous Tresca model and then in finite dimension with Coulomb friction for an arbitrary finite element method.

Solving Frictional Contact Problems with Multigrid Efficiency
The construction of fast and reliable solvers for contact problems with friction is even nowadays a challenging task. It is well known that contact problems with Coulomb friction have the weak form of a quasi-variational inequality [KO88, HHNL88, NJH80]. For small coefficients of friction, a solution can be obtained by means of a fixed point iteration in the boundary stresses [NJH80]. This fixe...
متن کاملQualitative analysis of 3D elastostatic contact problems with orthotropic Coulomb friction and solution-dependent coefficients of friction
This paper analyzes a discrete form of 3D contact problems with local orthotropic Coulomb friction and coefficients of friction which may depend on the solution itself. The analysis is based on the fixed-point reformulation of the original problem. Conditions guaranteeing the existence and uniqueness of discrete solutions are established. Finally, numerical results of a model example are presen...
متن کاملLarge-Scale Parallel Multibody Dynamics with Frictional Contact on the Graphical Processing Unit
In the context of simulating the frictional contact dynamics of large systems of rigid bodies, this paper reviews a novel method for solving large cone complementarity problems by means of a fixed-point iteration algorithm. The method is an extension of the Gauss-Seidel and Gauss-Jacobi methods with overrelaxation for symmetric convex linear complementarity problems. Convergent under fairly sta...
متن کاملSystem identification of a beam with frictional contact
The nonlinear system becomes an area with numerous investigations over the past decades. The conventional modal analysis could not be applied on nonlinear continuous system which makes it impossible to construct the reduced order models and obtain system response based on limited number of measurement points. Nonlinear normal modes provide a useful tool for extending modal analysis to nonlinea...
متن کاملPressure Masks for Point-like Contact with Elastic Models
In this paper, we introduce pressure masks for supporting the convenient abstraction of localized scale-specific point-like contact with a discrete elastic object. While these masks may be defined for any elastic model, special attention is given to the case of point-like contact with precomputed linear elastostatic models for purposes of haptic force-feedback.
