The Biot stress -- right stretch relation for the compressible Neo-Hooke-Ciarlet-Geymonat model and Rivlin's cube problem
Ionel-Dumitrel Ghiba, Franz Gmeineder, Sebastian Holthausen +2
The aim of the paper is to recall the importance of the study of invertibility and monotonicity of stress-strain relations for investigating the non-uniqueness and bifurcation of h…
Rayleigh waves in isotropic elastic materials with micro-voids
Emilian Bulgariu, Ionel-Dumitrel Ghiba, Hassam Khan +1
In this paper, we show that a general method introduced by Fu and Mielke allows to give a complete answer on the existence and uniqueness of a subsonic solution describing the prop…
Explicit formula for the Gamma-convergence homogenized quadratic curvature energy in isotropic Cosserat shell models
Maryam Mohammadi Saem, Emilian Bulgariu, Ionel-Dumitrel Ghiba +1
We show how to explicitly compute the homogenized curvature energy appearing in the isotropic -limit for flat and for curved initial configuration Cosserat shell models, when a…
A linear isotropic Cosserat shell model including terms up to . Existence and uniqueness
Ionel-Dumitrel Ghiba, Mircea Birsan, Patrizio Neff
In this paper we derive the linear elastic Cosserat shell model incorporating effects up to order in the shell thickness as a particular case of the recently introduce…
A panorama of dispersion curves for the weighted isotropic relaxed micromorphic model
Marco Valerio d'Agostino, Gabriele Barbagallo, Ionel-Dumitrel Ghiba +2
We consider the weighted isotropic relaxed micromorphic model and provide an in depth investigation of the characteristic dispersion curves when the constitutive parameters of the…
Rank-one convexity implies polyconvexity in isotropic planar incompressible elasticity
Ionel-Dumitrel Ghiba, Robert J. Martin, Patrizio Neff
We study convexity properties of energy functions in plane nonlinear elasticity of incompressible materials and show that rank-one convexity of an objective and isotropic elastic e…
