On the application of the SCD semismooth* Newton method to variational inequalities of the second kind
Helmut Gfrerer, Jiri V. Outrata, Jan Valdman
The paper starts with a description of the SCD (subspace containing derivative) mappings and the SCD semismooth* Newton method for the solution of general inclusions. This method i…
Linearization and Computation for Large-Strain Viscoelasticity
Patrick Dondl, Martin Jesenko, Martin Kružík +1
Time-discrete numerical minimization schemes for simple viscoelastic materials in the large strain Kelvin-Voigt rheology are not well-posed due to non-quasiconvexity of the dissipa…
Fast MATLAB evaluation of nonlinear energies using FEM in 2D and 3D: nodal elements
Alexej Moskovka, Jan Valdman
Nonlinear energy functionals appearing in the calculus of variations can be discretized by the finite element (FE) method and formulated as a sum of energy contributions from local…
On the solution of contact problems with Tresca friction by the semismooth* Newton method
Helmut Gfrerer, Jiri V. Outrata, Jan Valdman
An equilibrium of a linear elastic body subject to loading and satisfying the friction and contact conditions can be described by a variational inequality of the second kind and th…
Minimization of p-Laplacian via the Finite Element Method in MATLAB
Ctirad Matonoha, Alexej Moskovka, Jan Valdman
Minimization of energy functionals is based on a discretization by the finite element method and optimization by the trust-region method. A key tool is a local evaluation of the ap…
