We investigated the possibility of controlling thin film buckling patterns by varying the substrate curvature and the stress induced therein upon cooling. The numerical and experimental studies are based on a spherical Ag core/SiO(2) shell system. For Ag substrates with a relatively larger curvature, the dentlike triangular buckling pattern comes out when the film nominal stress exceeds a criti...

Damage to structural walls in the recent earthquakes in Chile (2010) and New Zealand (2011) demonstrated that modern reinforced concrete (RC) wall behaviour can be largely governed by out-of-plane displacements triggered by instability. Thin walls are the most vulnerable to this deformation mechanism, especially if they have a single layer of reinforcement. These wall types can be easily found ...

The advancement in steel fabrication technology extends the structural and constructional advantages of cellular beams into arched structure members. However, less attention is given to understanding in-plane out-of-plane behavior performance beams. This article presents a numerical study using finite element package ABAQUS investigate effect arch axis geometry (circular parabolic) impact end s...

The paper discusses the experimental and finite element investigation into the failure mechanisms of uniply graphite-epoxy composite plates with circular holes loaded in uniaxial compression. The effect of hole size on the failure mode is established. Test specimens composed of a single layer of uniply graphite-epoxy sandwiched between two layers of transparent polyetherimide plastic were desig...

This paper presents a 3D direct numerical simulation of buckled thin-film packaging based on transferred elastic wrinkling bonded compliant polymer ring. The mode change the fabricated cap is found by measuring shape at different times after Si substrate debonding. conventional linear and nonlinear buckling simulations are not adequate to understand behavior mechanism creating such change. Dire...

In this study, by using the first-principles calculations based on density functional theory (DFT), electronic aspects of GeP2S monolayer under effect buckling variation parameter (μ = 0, 2, 4, 6) are theoretically investigated PBE-GGA approximation method, and obtained results have been compared with previous similar structures. The imaginary part dielectric function absorption spectra is pres...
