In this theoretical study, it is presented that the electronic behavior and mechanical characteristics of CuGa5S8 compound having face centered cubic structure with space group F4 ̅3m number 216. All calculations based on density functional theory (DFT) were performed by Generalized Gradient Approximation (GGA). It understood from observed band system has semiconducting close to zero-band gap. A...

Abstract The effect of aging on the mechanical properties silicone rubber (SR) was investigated by means ultrasonic, dynamic analysis, and FTIR techniques. Both longitudinal shear (Ultrasonic wave velocities) were measured at room temperature frequencies 2 MHz. Density, molar volume, ultrasonic velocities, tensile strength, properties, FT–IR showed improvement network with time from 0 to 70 day...

This research paper provides an analysis for the deformation and vertical stiffness of non-pneumatic tyres (NPT) due to different loads. The are developed replacing traditional pneumatic tyres. These do not use air support load subjected hard conditions rough terrain. used heavy load-carrying capacity, stiffness, contact pressure, rolling. mechanical characteristics NPT studied by using a 3D mo...

The available literature identifies that the addition of mineral admixture as partial replacement of cement improves the microstructure of the concrete (i.e., porosity and pore size distribution) as well as increasing the mechanical characteristics such as drying shrinkage and creep, compressive strength, tensile strength, flexural strength, and modulus of elasticity; however, no single documen...

Bone cements produced by different manufacturers vary in their mechanical properties and antibiotic elution characteristics. Small changes in the formulation of a bone cement, which may not be apparent to surgeons, can also affect these properties. The supplier of Palacos bone cement with added gentamicin changed in 2005. We carried out a study to examine the mechanical characteristics and anti...

Recent developments in the study of the laser bending process are reviewed and presented to obtain new perspectives along the lines of dimensional characteristics and mechanical properties of the formed parts. Both numerical and experimental results are described and compared. The dimensional characteristics examined include bending angle variation and bending edge curving. The mechanical prope...
