Global injectivity in second-gradient Nonlinear Elasticity and its approximation with penalty terms
Stefan Krömer, Jan Valdman
We present a new penalty term approximating the Ciarlet-Nečas condition (global invertibility of deformations) as a soft constraint for hyperelastic materials. For non-simple mater…

Interfacial polyconvex energy-enhanced evolutionary model for shape memory alloys
Miroslav Frost, Martin Kružík, Jan Valdman
A sharp-interface model describing static equilibrium configurations of shape mory alloys by means of interfacial polyconvex energy density introduced by Šilhavý in 2010 and extend…

Efficient and flexible MATLAB implementation of 2D and 3D elastoplastic problems
Martin Čermák, Stanislav Sysala, Jan Valdman
We propose an effective and flexible way to implement 2D and 3D elastoplastic problems in MATLAB using fully vectorized codes. Our technique is applied to a broad class of the prob…
