The current study investigates the interaction of a piezoelectric dislocation with a multi-layered coated fiber inhomogeneity embedded in an infinite piezoelectric solid. In our study, three dissimilar material phases are involved: the matrix, the inclusion and the multi-layered coating layers....

Ring vibration analysis is more challenging than straight beams analysis. In straight beams, the structural deformations depend on rotational and translational displacements; however, in rings, in addition to these, they also depend on the coupled tangential displacement caused by the curvature...

Abstract—Viscoelastic materials are commonly used for engineering applications due to their unique and useful properties. Namely, when rubbers are subjected to deformation, then the stress response is not linear but increases or decreases similar to a hyperelastic material. Moreover, the...

In the present study, we investigate the roles of interface and interfiber interactions on the toughening and failure mechanisms of nanofibrillated rubber-toughened thermoplastic-based nanocomposites. Emphasis is placed on establishing a comprehensive theoretical and atomistic descriptions of the...

Abstract—Tornados are a major hazard and ever-present threat in many regions, with the potential to cause wide-scale loss of life and damage to infrastructure. Many researchers have attempted to develop tornado simulation techniques that amount to vortex generation with the goal of understanding...

High-resolution imaging of deformation processes in materials under load requires controllable and stable loading conditions and the ability to vary sample orientation relative to the imaging source. A novel tensile testing apparatus has been designed, developed, and characterized for...

This paper aims to evaluate the effect of porosity and buoyancy on the natural convection of CuO-RT25 nano- enhanced phase change material (NePCM) in a differentially heated porous square cavity. Buongiorno’s two-phase model is utilized to consider the Brownian thermophoresis diffusion of...

It has been widely accepted that stress and strain fields near the crack tip govern crack propagation behavior. In most cases, an elasto-plastic analysis is required to determine local stress and strain fields around the crack tip due to the high stress concentration. However, complexities of...

We study the evolution of chaotic mixing in an initially stratified circular vessel. The bottom and top halves of the vessel are filled with viscoplastic and Newtonian fluids. A circular stirrer in the vessel promotes the mixing. We considered three different viscosity ratios to understand the...
