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 ...

Numerical aspects of computational homogenization [PDF]
Computer Methods in Materials Science, 2013 Computational homogenization enables replacement of a heterogeneous domain by an equivalent body with effective material parameters. Approach that we use is based on two-scale micro/macro analysis.

A Finite Volume Method to Solve the Ill-Posed Elliptic Problems
Mathematics, 2022 In this paper, we propose a finite volume element method of primal-dual type to solve the ill-posed elliptic problem, that is, the elliptic problem with lacking or overlapping boundary value condition.

Damage Detection in Beam-like Structures Applying Finite Volume Method [PDF]
Journal of Rehabilitation in Civil Engineering, 2017 In this article, a damage location in beam like-structure is determined using static and dynamic data obtained applying the finite volume method. The modification of static and dynamic displacement due to damage is applied to establish an indicator for ...
