DOI: 10.1007/s00707-016-1765-4
Abstract: The phononic band structure of waves, which travel though composites, results from the geometric and mechanical properties of the materials and from the interaction of the different constituents. In this article, we study two different… read more here.

DOI: 10.1007/s11587-017-0325-0
Abstract: We consider the superimposition of two shear waves on a pseudo-plane motion of the first kind with elliptical streamlines. If the shear waves satisfy some special assumptions it is possible to establish a recurrence relation… read more here.

DOI: 10.1007/s13369-016-2332-y
Abstract: The influence of the combined effect of initial stress and periodic surface corrugation on ultrasonic SH wave propagation in an elastic plate is investigated. Considering weak surface corrugations, a small parameter is defined using the… read more here.

DOI: 10.1016/j.wavemoti.2018.10.004
Abstract: Abstract Despite accounting for certain loss mechanisms, model equations for nonlinear compressional and shear waves may predict waveform overturning (multivalued waveforms) when the source amplitude exceeds a critical value. Waveform overturning reveals that essential physics… read more here.

DOI: 10.1063/5.0150219
Abstract: In the field of acoustics, a medium has traditionally been considered a liquid if shear waves cannot propagate. For more complex liquids, such as those containing polymer chains or surfactant aggregates, this definition begins to… read more here.
