Corner reflectors form the major scattering centers in the radar signatures of ships, aircraft and vehicles. The radar cross section (RCS) reduction of these "flare spots" (corner reflectors) plays an ...

In this video we explore bending and shear stresses in beams. A bending moment is the resultant of bending stresses, which ...

Imagine a liquid that flows freely one moment, then stiffens into a near-solid the next, and then can switch back with a ...

Abstract When a semicrystalline polymer melt is subjected to sufficient flow before crystallization, the nucleation rate is accelerated. In this study, the degree of acceleration is investigated with ...

One of the most important nonlinear rheological phenomena in flowing polymeric materials is the stress overshoot under start-up shear at sufficiently high shear rates γ̇, i.e., γ̇ > τd–1, where τd is ...

We rarely think about how liquids flow—why honey is thick, water is thin or how molten plastic moves through machines. But ...

This work aims to investigate the transverse free vibration of non-uniform beams with exponentially varying rectangular and circular cross-sections. When solving the governing equations for ...
