Material sensitivity analysis in homogenization of linear elastic composites

Archive of Applied Mechanics (Ingenieur Archiv), 2001
The author considers an heterogeneous elastic material assuming that the inclusions, which are periodically distributed, are built of a finite number of different disjoint materials. All the materials which are involved (the matrix and the inclusions) are supposed to be linear and transversely isotropic elastic materials.

Asymptotic analysis and boundary homogenization in linear elasticity

Mathematical Methods in the Applied Sciences, 2000
The authors consider a linear elastic problem posed in a domain of \(\mathbb{R}^3\) with homogeneous Dirichlet conditions imposed on small zones of \(\varepsilon\)-size \((\varepsilon\to 0)\) distributed on the boundary of the domain. Using the concept of a rich family of Borel subsets of the boundary and the epi-convergence arguments, they obtain the ...

The comparative analysis of the fully nonlinear, the linear elastic and the consistently linearized equations of motion of the 2D elastic pendulum

Computers & Structures, 2004
The floating frame of reference approach is used for the analysis of the in-plane oscillations of the suspended rectangular plate. The deformation is interpolated by means of polynomial shape functions. The equations of motion become nonlinear in the deformation degrees of freedom both due to the geometrically nonlinear deformation model and to the ...

Analysis of a Crack Embedded in a Linear Elastic Half-Plane Solid

Journal of Applied Mechanics, 1995
A crack embedded in a half-plane solid traction-free on the infinite straight boundary is analyzed. The response of the material is linear elastic. A system of singular integral equations for the unknown dislocation densities defined on the crack faces is derived.

Wellbore Stability Analysis: From Linear Elasticity to Postbifurcation Modeling

International Journal of Geomechanics, 2004
This paper reviews some of the progress made on wellbore stability modeling during the last two decades. First we demonstrate the improvement made on mud-pressure predictions by moving from analytic elastic solutions to finite element elastoplastic modeling.

THERMOELASTIC STRESS ANALYSIS FOR LINEAR ELASTIC BODIES

2006
The stress analysis for elastic cylinders made of polymethylmethacrylate (PMMA) under cyclic loading is provided by using FEM. Under the assumption that the elastic moduli depend linearly on the temperature, new fomulae, generalizing the well known Kelvin's formula, are given such that we can estimate the temperature variation on the external surface ...

Squeezing instabilities and delamination in elastic bilayers: A linear stability analysis

Physical Review E, 2012
A linear stability analysis is presented to understand the instabilities that arise in an elastic bilayer, consisting of a very thin bottom layer (thickness < 100 nm) that acts as a wetting film and a top layer that acts as an adhesive film, when placed in contact proximity with an external rigid contactor.
