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

P Lewintan, S Müller, P Neff - Calculus of Variations and Partial Differential …, 2021 - Springer
Abstract Let Ω⊂ R 3 be an open and bounded set with Lipschitz boundary and outward unit
normal ν. For 1< p<∞ we establish an improved version of the generalized L p-Korn …

Nečas–Lions lemma revisited: An Lp‐version of the generalized Korn inequality for incompatible tensor fields

P Lewintan, P Neff - Mathematical Methods in the Applied …, 2021 - Wiley Online Library
For 1< p<∞, we prove an L p‐version of the generalized Korn inequality for incompatible
tensor fields P in W 0 1, p (Curl; Ω, ℝ 3× 3). More precisely, let Ω⊂ ℝ 3 be a bounded …

Gaussian curvature as an identifier of shell rigidity

D Harutyunyan - Archive for Rational Mechanics and Analysis, 2017 - Springer
In the paper we deal with shells with non-zero Gaussian curvature. We derive sharp Korn's
first (linear geometric rigidity estimate) and second inequalities on that kind of shell for zero …

On the Korn interpolation and second inequalities in thin domains

D Harutyunyan - SIAM Journal on Mathematical Analysis, 2018 - SIAM
We consider shells of nonconstant thickness in three dimensional Euclidean space around
surfaces which have bounded principal curvatures. We derive Korn's interpolation inequality …

Korn and Poincaré-Korn inequalities: A different perspective

G Di Fratta, F Solombrino - Proceedings of the American Mathematical …, 2025 - ams.org
We present a concise point of view on the first and the second Korn's inequality for general
exponent $ p $ and for a class of domains that includes Lipschitz domains. Our argument is …

Optimal exponentials of thickness in Korn's inequalities for parabolic and elliptic shells

PF Yao - Annali di Matematica Pura ed Applicata (1923-), 2021 - Springer
We consider the scaling of the optimal constant in Korn's first inequality for elliptic and
parabolic shells which was first given by Grabovsky and Harutyunyan with hints coming from …

Mixed boundary value problems for the elasticity system in exterior domains

HA Matevossian - Mathematical and Computational Applications, 2019 - mdpi.com
We study the properties of solutions of the mixed Dirichlet–Robin and Neumann–Robin
problems for the linear system of elasticity theory in the exterior of a compact set and the …

The Buckling Load of Cylindrical Shells Under Axial Compression Depends on the Cross-Sectional Curvature

D Harutyunyan, AM Rodrigues - Journal of Nonlinear Science, 2023 - Springer
It is known that the famous theoretical formula by Koiter for the critical buckling load of
circular cylindrical shells under axial compression does not coincide with the experimental …

[HTML][HTML] The asymptotically sharp Korn interpolation and second inequalities for shells

D Harutyunyan - Comptes Rendus Mathematique, 2018 - Elsevier
We consider shells in three-dimensional Euclidean space that have bounded principal
curvatures. We prove Korn's interpolation (or the so-called first and a half 1) and the second …

Sharp weighted Korn and Korn-like inequalities and an application to washers

D Harutyunyan - Journal of Elasticity, 2017 - Springer
In this paper we prove asymptotically sharp weighted “first-and-a-half” 2 D 2D Korn and Korn-
like inequalities with a singular weight occurring from Cartesian to cylindrical change of …
