MATLAB implementation of hp finite elements on rectangles
Alexej Moskovka, Jan Valdman
A simple MATLAB implementation of hierarchical shape functions on 2D rectangles is explained and available for download. Global shape functions are ordered for a given polynomial d…
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…
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…
On the application of the semismooth* Newton method to variational inequalities of the second kind
Helmut Gfrerer, Jiri V. Outrata, Jan Valdman
The paper starts with a concise description of the recently developed semismooth* Newton method for the solution of general inclusions. This method is then applied to a class of va…
On computation of optimal strategies in oligopolistic markets respecting the cost of change
Jiří V. Outrata, Jan Valdman
The paper deals with a class of parametrized equilibrium problems, where the objectives of the players do possess nonsmooth terms. The respective Nash equilibria can be characteriz…
MATLAB Implementation of Element-based Solvers
Leszek Marcinkowski, Jan Valdman
Rahman and Valdman (2013) introduced a vectorized way to assemble finite element stiffness and mass matrices in MATLAB. Local element matrices are computed all at once by array ope…
