In this paper, a rectangular sandwich plate with a constrained layer and an electrorheological (ER) fluid core is investigated. The rectangular plate is covered an ER fluid core and a constraining layer to improve the stability of the system. The two outer layers of the sandwich structure are elastic. The viscoelastic materials express the middle layer behavior under electric field and small st...

The relationship between structural and low-temperature transport properties is explored for InxAl1-xAs/InxGa1-xAs metamorphic quantum wells with x > 0.7 grown on GaAs by molecular beamepitaxy. Different step-graded buffer layers are used to gradually adapt the in-plane latticeparameter from the GaAs towards the InGaAs value. We show that using buffer layers with asuitable maxim...

This paper analyses the influence of residual stresses and strain hardening due to the cold rollforming process on the load carrying capacity of perforated rack columns. First of all, a residual strain distribution of the manufacturing process is obtained via a finite element analysis and then it is introduced in the model as initial state to carry out a nonlinear buckling analysis. Two differe...

this study was designed to evaluate the efficacy of beta-cyfluthrin (responsar 12.5% sc), against a standard susceptible strain of german cockroach, blattella germanica, using three different dosages, at three different exposure times, on two types of surface, parlous (mosaic) and non parous (glassed ceramic of tiles). comparison of the resifts indicated that beta-cyfluthrin at 12.5 a.i.mg/m2, ...

Residual strains in ferroelectrics are known to adversely affect the material properties by aggravating crack growth and fatigue degradation. The primary cause for residual strains is strain incompatibility between different microstructural entities. For example, it was shown in polycrystalline ferroelectrics that residual strains are caused due to incompatibility between the electric-field-ind...

ABSTRACT- Bruising degrades the quality of fresh apple fruits. Reducing bruise damage is of utmost importance in designing and developing processing equipments. The main objective of the present study was to introduce an analytical method to predict the allowable static load applicable to apple fruits. To predict the strain energy absorbed by the fruit, a point load was applied on the solid sph...
