Korn inequalities for incompatible tensor fields in three space dimensions with conformally invariant dislocation energy

Peter Lewintan, Stefan Müller, Patrizio Neff

Let $Ω \subset R^{3}$ be an open and bounded set with Lipschitz boundary and outward unit normal $ν$ . For $1 < p < \infty$ we establish an improved version of the generalized $L^…

A constrained Cosserat shell model up to order $O (h^{5})$ : Modelling, existence of minimizers, relations to classical shell models and scaling invariance of the bending tensor

Ionel-Dumitrel Ghiba, Mircea Bîrsan, Peter Lewintan +1

We consider a recently introduced geometrically nonlinear elastic Cosserat shell model incorporating effects up to order $O (h^{5})$ in the shell thickness $h$ . We develop the corresp…

$L^{p}$ -trace-free generalized Korn inequalities for incompatible tensor fields in three space dimensions

Peter Lewintan, Patrizio Neff

For $1 < p < \infty$ we prove an $L^{p}$ -version of the generalized trace-free Korn inequality for incompatible tensor fields $P$ in $ W^{1,\,p}_0(\operatorname{Curl}; Ω,\mathbb{R}^{3\ti…

The isotropic Cosserat shell model including terms up to $O (h^{5})$ . Part II: Existence of minimizers

Ionel-Dumitrel Ghiba, Mircea Bîrsan, Peter Lewintan +1

We show the existence of global minimizers for a geometrically nonlinear isotropic elastic Cosserat 6-parameter shell model. The proof of the main theorem is based on the direct me…

The isotropic Cosserat shell model including terms up to $O (h^{5})$ . Part I: Derivation in matrix notation

Ionel-Dumitrel Ghiba, Mircea Bîrsan, Peter Lewintan +1

We present a new geometrically nonlinear Cosserat shell model incorporating effects up to order $O (h^{5})$ in the shell thickness $h$ . The method that we follow is an educated 8-para…
