Equilibrated tractions for the Hybrid High-Order method [PDF]
, 2014 We show how to recover equilibrated face tractions for the hybrid high-order method for linear elasticity recently introduced in [D. A. Di Pietro and A. Ern, A hybrid high-order locking-free method for linear elasticity on general meshes, Comput.

A higher order control volume based finite element method to prodict the deformation of heterogeneous materials [PDF]
, 2013 Materials with obvious internal structure can exhibit behaviour, under loading, that cannot be described by classical elasticity. It is therefore important to develop computational tools incorporating appropriate constitutive theories that can capture ...

Uniform Domain Equilibrium Equation with Finite Deformations [PDF]
E3S Web of Conferences, 2023 In corner areas of structures, high stress values and gradients occur, and lead to stress concentrations. Infinite stress and deformations are determined by a solution of the linear elasticity theory problem in the area with a wedge-shape boundary notch.

On near-cloaking for linear elasticity [PDF]
, 2019 We make precise some results on the cloaking of displacement fields in linear elasticity. In the spirit of transformation media theory, the transformed governing equations in Cosserat and Willis frameworks are shown to be equivalent to certain high ...

Convergence of a cell-centered finite volume discretization for linear elasticity [PDF]
, 2015 We show convergence of a cell-centered finite volume discretization for linear elasticity. The discretization, termed the MPSA method, was recently proposed in the context of geological applications, where cell-centered variables are often preferred. Our

Linear models of income patterns in consumer demand for foods and evaluation of its elasticity
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2005 The paper is focused on the use of the linear constructions for developing of Engel’s demand models in the field of the food-consumer demand. In the theoretical part of the paper, the linear approximations of this demand models are analysed on the bases ...

Gradient Schemes for Linear and Non-linear Elasticity Equations
, 2014 The Gradient Scheme framework provides a unified analysis setting for many different families of numerical methods for diffusion equations. We show in this paper that the Gradient Scheme framework can be adapted to elasticity equations, and provides ...
