Homogenization of perforated elastic structures

G Griso, L Khilkova, J Orlik, O Sivak - Journal of Elasticity, 2020 - Springer
The paper is dedicated to the asymptotic behavior of ε $\varepsilon$ -periodically perforated
elastic (3-dimensional, plate-like or beam-like) structures as ε → 0 $\varepsilon \to 0$ . In …

On the secondary stability of coated cementless hip replacement: parameters that affected interface strength

J Orlik, A Zhurov, J Middleton - Medical engineering & physics, 2003 - Elsevier
Unlike primary stability of coated cementless implants, their secondary stability has been
poorly studied. This paper considers some theoretical aspects of the secondary stability of a …

Asymptotic behavior of stable structures made of beams

G Griso, L Khilkova, J Orlik, O Sivak - Journal of Elasticity, 2021 - Springer
In this paper, we study the asymptotic behavior of an ε $\varepsilon $ -periodic 3D stable
structure made of beams of circular cross-section of radius r $r$ when the periodicity parameter …

[HTML][HTML] Recent efforts in modeling and simulation of textiles

J Orlik, M Krier, D Neusius, K Pietsch, O Sivak… - Textiles, 2021 - mdpi.com
In many textiles and fiber structures, the behavior of the material is determined by the structural
arrangements of the fibers, their thickness and cross-section, as well as their material …

Asymptotic analysis for domains separated by a thin layer made of periodic vertical beams

G Griso, A Migunova, J Orlik - Journal of Elasticity, 2017 - Springer
We consider a thin heterogeneous layer consisting of thin beams (of radius r $r$ ) and study
the limit behavior of this problem as the period ε $\varepsilon $ , the thickness δ $\delta$ …

Asymptotic Behavior of Unstable Structures Made of Beams

G Griso, L Khilkova, J Orlik - Journal of Elasticity, 2022 - Springer
In our previous papers (Griso et al. in J. Elast. 141:181–225, 19 ; J. Elast., 23 , https://doi.org/10.1007/s10659-021-09816-w
), we considered thick periodic structures (first paper) and …

[HTML][HTML] On the ultimate strength of heterogeneous slender structures based on multi-scale stress decomposition

J Orlik, D Neusius, K Steiner, M Krier - International Journal of Engineering …, 2024 - Elsevier
This paper presents an algorithm based on asymptotic methods for computing the effective
ultimate and high cyclic fatigue strength of heterogeneous periodic plates, shells, and textiles. …

Homogenization via unfolding in periodic elasticity with contact on closed and open cracks

D Cioranescu, A Damlamian, J Orlik - Asymptotic Analysis, 2013 - content.iospress.com
We consider the elasticity problem in a heterogeneous domain with an ε-periodic micro-structure,
ε<< 1, including multiple micro-contacts between the structural components. These …

A one‐dimensional computational model for hyperelastic string structures with Coulomb friction

V Shiryaev, J Orlik - Mathematical Methods in the Applied …, 2017 - Wiley Online Library
In this paper, we consider a new model for the simulation of textiles with frictional contact
between fibers and no bending resistance. In the model, one‐dimensional hyperelasticity and …

Asymptotic behavior for textiles in von-Kármán regime

G Griso, J Orlik, S Wackerle - Journal de Mathématiques Pures et …, 2020 - Elsevier
This paper is dedicated to the investigation of simultaneous homogenization and dimension
reduction of textile structures as elasticity problem with an energy in the von-Kármán-regime…
