Dimension reduction for a coupled electro-elastic saddle-point problem at finite strains

Kateryna Buryachenko, Annegret Glitzky, Matthias Liero +1

We study the finite deformation of a thin, elastically heterogeneous sheet subject to electrostatic coupling. The interaction between mechanics and electrostatics is formulated as…

Derivation of the Reissner-Mindlin model from nonlinear elasticity

Tamara Fastovska, Janusz Ginster, Barbara Zwicknagl

We discuss how the Reissner-Mindlin plate model can be derived from three-dimensional finite elasticity in terms of -convergence. The presence of transverse shear effects in th…

Nonlinear interpolation inequalities with fractional Sobolev norms and pattern formation in biomembranes

Janusz Ginster, Anastasija Pešić, Barbara Zwicknagl

We consider a one-dimensional version of a variational model for pattern formation in biological membranes. The driving term in the energy is a coupling between the order parameter…

Microstructures in a two-dimensional frustrated spin system: Scaling regimes and a discrete-to-continuum limit

Janusz Ginster, Melanie Koser, Barbara Zwicknagl

We study pattern formation within the - - spin model on a two-dimensional square lattice in the case of incompatible (ferromagnetic) boundary conditions on the spin field…

On the Effect of Geometry on Scaling Laws for a Class of Martensitic Phase Transformations

Janusz Ginster, Angkana Rüland, Antonio Tribuzio +1

We study scaling laws for singular perturbation problems associated with a class of two-dimensional martensitic phase transformations and deduce a domain dependence of the scaling…
