Wave Motion and Stop-Bands in Pipes with Helical Characteristics Using Wave Finite Element Analysis

Pipes are widely used in many industrial and mechanical applications and devices. Although there are many different constructions according to the specific application and device, these can show helical pattern, such as spiral pipes, wire-reinforced pipes/shells, spring-suspension, and so on. Theoretical modelling of wave propagation provides a prediction about the dynamic behavior, and it is f...

Wave Motion

Examples: Sound waves (pressure waves) in air (or in any gas or solid or liquid) Waves on a stretched string Waves on the surface of water "The Wave" at the ballpark stadium. The medium is the people. Electromagnetic waves (light) – this is the only kind of wave which does not require a medium. EM waves can travel in vacuum. This was quite a surprise to 19 th century physicists who had trouble ...

Analysis of Wave Motion in a Micropolar Transversely Isotropic Medium

The present investigation deals with the propagation of waves in a micropolar transversely isotropic layer. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are derived. The amplitudes of displacements and microrotation were also obtained. Finally, the numerical solution was carried out for aluminium epoxy material and the dispersion curv...
