the problem of propagation of plane wave including body and surface waves propagating in a transversely isotropic half-space with a depth-wise axis of material symmetry is investigated in details. using the advantage of representation of displacement fields in terms of two complete scalar potential functions, the coupled equations of motion are uncoupled and reduced to two independent equations...

The acoustic wave velocity depends on elasticity and density at most materials, but because of anisotropy and especially piezoelectric coupling effect, the acoustic wave propagation at piezoelectric based crystalloacoustic materials, is an applied and challenging problem. In this paper, using modified Christoffel's equation based on group velocity concept, the effect of anisotropy and piezoelec...
The article touches a physically interesting phenomena of half-frequency edge waves. Results look interesting and useful in the context of shore wave dynamics. A few points need to be expanded though. 1) It is worth presenting the raw data explicitly displaying the period doubling effect. ADV versus wave gauges? Difference between wave gauge reading? 2) The flume is narrow hence parameters of t...
Abstract A two-dimensional numerical simulation is performed in the present work to study the structure of a detonation wave in high activation energy mixtures, which are characterized by their turbulent reaction zone structure and unreacted pockets. The process of transverse wave and triple point collision with the channel walls, formation and consumption mechanism of unburnt gas pockets is e...
The linear governing equations of a transversely isotropic microstretch elastic solid medium are formulated and solved for surface wave solutions. The appropriate solutions satisfying the radiation conditions are applied to the required boundary conditions at the free surface of the halfspace of the medium. A frequency equation is obtained for Rayleigh surface wave in the medium. The non-dimens...
Recents results in Physics beyond the Standard Model at the e + p collider HERA with the H1 and ZEUS detectors are presented. As no evidence for excited fermions or MSSM supersymmetric particles has been found using an integrated luminosity up to 20 pb ?1 , new limits are derived. The status of events with an isolated high energy lepton and missing transverse momentum is also reported.
