Parallel Solution of Elastoplastic Problems with Numerical Experiments

چکیده
In this paper we present efficient parallel implementation of solvers for elastoplastic problems based on the so-called Total Finite Element Tearing and Interconnecting (TFETI) domain decomposition method. We propose a set of numerical experiments to illustrate effectivity of the presented solvers. We consider an associated elastoplastic model with the von Misses plastic criterion and the isotropic or kinematic hardening law. The semi smooth Newton method is applied to solve this nonlinear system. Corresponding linearized problems arising in the Newton iterations are solved in parallel by the above mentioned TFETI domain decomposition method. The proposed TFETI based algorithm was implemented using PETSc and its performance is illustrated on a 3D elastoplastic benchmark. Numerical results for different scalability and mesh levels are presented and discussed.

Efficient numerical methods for the large-scale, parallel solution of elastoplastic contact problems
Quasi-static elastoplastic contact problems are ubiquitous in many industrial processes and other contexts, and their numerical simulation is consequently of great interest in accurately describing and optimizing production processes. The key component in these simulations is the solution of a single load step of a time iteration. From a mathematical perspective, the problems to be solved in ea...
متن کاملCommon solutions to pseudomonotone equilibrium problems
In this paper, we propose two iterative methods for finding a common solution of a finite family of equilibrium problems for pseudomonotone bifunctions. The first is a parallel hybrid extragradient-cutting algorithm which is extended from the previously known one for variational inequalities to equilibrium problems. The second is a new cyclic hybrid extragradient-cutting algorithm....
متن کاملNew Numerical Solver for Elastoplastic Problems based on the Moreau-Yosida Theorem
We discuss a new solution algorithm for solving elastoplastic problems with hardening. The one time-step elastoplastic problem can be formulated as a convex minimization problem with a continuous but non-smooth functional dependening on unknown displacement smoothly and on the plastic strain non-smoothly. It is shown that the functional structure allows the application of the Moreau-Yosida Theo...

The plastic zone developed during elastoplastic contact may be effectively modeled as an inclusion in an isotropic half space. This paper proposes a simple but efficient computational method to analyze the stresses caused by near surface inclusions of arbitrary shape. The solution starts by solving a corresponding full space inclusion problem and proceeds to annul the stresses acting normal and...

We propose an algorithm for the efficient parallel implementation of elastoplastic problems with hardening based on the so-called TFETI (Total Finite Element Tearing and Interconnecting) domain decomposition method. We consider an associated elastoplastic model with the von Mises plastic criterion and the linear isotropic hardening law. Such a model is discretized by the implicit Euler method i...
