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...

Solid oxide fuel cell (SOFC) is a promising clean technology to generate power with high efficiency at different scales. Decreasing the degradation rate of SOFCs is a challenge that can be tackled by lowering the operation temperature (<650°C). However, this can adversely affect cell performance...

Crack-tip stress evaluation requires special treatments in the frame of classical elasticity theory for characterizing fatigue crack growth behavior. In previous studies, modified finite element methods have been used to remedy infinite stresses predicted by the classical elasticity theory at the...
