Homogenization of sandwich panels

open access: yesComputer Assisted Methods in Engineering and Science, 2017
The numerical modeling of plates with periodic corrugation requires some efforts to be made in terms of careful and precise discretization of the complicated structure. This automatically generates very computationally expensive models.

Numerical Homogenization of the Acoustic Wave Equations with a Continuum of Scales [PDF]

open access: yes, 2008
In this paper, we consider numerical homogenization of acoustic wave equations with heterogeneous coefficients, namely, when the bulk modulus and the density of the medium are only bounded.

Elastic Analysis of Three-Layer Concrete Slab Based on Numerical Homogenization with an Analytical Shear Correction Factor

open access: yesApplied Sciences, 2022
Sandwich structures are widely used in construction, as well as in the aviation, spaceship, and electronics industries. The interesting result, among others, is the fact that individual layers can be freely selected to meet the planned requirements.

Finite Element Approximation of Elliptic Homogenization Problems in Nondivergence-Form

open access: yes, 2019
We use uniform $W^{2,p}$ estimates to obtain corrector results for periodic homogenization problems of the form $A(x/\varepsilon):D^2 u_{\varepsilon} = f$ subject to a homogeneous Dirichlet boundary condition.

Localized bases for finite dimensional homogenization approximations with non-separated scales and high-contrast [PDF]

open access: yes, 2010
We construct finite-dimensional approximations of solution spaces of divergence form operators with $L^\infty$-coefficients. Our method does not rely on concepts of ergodicity or scale-separation, but on the property that the solution space of these ...

The Effects of Profile Errors of Microlens Surfaces on Laser Beam Homogenization

open access: yesMicromachines, 2017
Microlens arrays (MLAs) are key optical components in laser beam homogenization. However, due to imperfect surface profiles resulting from microfabrication, the functionalities of MLAs in beam modulation could be compromised to some extent.
