Interaction of Rayleigh waves with periodic baffles
Archives of Acoustics, 2002 Rayleigh waves in two solids separated by an air gap containing two alternate periodic in-plane baffle systems are considered. A Bragg reflection of the waves occurs when the distance between the baffle planes and between baffles and ...

On the existence of weakly nonlocal Rayleigh waves with impedance boundary condition
Archives of MechanicsIn this paper, the existence of Rayleigh waves propagating in weakly nonlocal incompressible isotropic elastic half-spaces subject to the tangential impedance boundary condition (TIBC) (at the surface of half-spaces, the tangential stress is proportional

Simulation of seismograms in a 2-D viscoelastic Earth by pseudospectral methods [PDF]
Geofísica Internacional, 2005 Using an improved global pseudospectral modeling algorithm we synthesize seismograms generated by oceanic and continental earthquakes. Attention is given to attenuation, to explicit modeling of boundary conditions at the ocean-bottom interface ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Understanding the dynamic behavior of structural components is crucial for optimizing performance and ensuring structural integrity. This study presents a new method that combines a systematic experimental investigation of four distinct hole geometries (circular, square, compact rectangular, and long rectangular) with varying hole counts, all ...

Surface waves in fibre-reinforced anisotropic solid elastic media under the influence of gravity
Journal of the Mechanical Behavior of Materials, 2012 The aim of the present article is to investigate the surface waves in anisotropic, elastic solid medium under the influence of gravity. The theory of generalised surface waves has first been developed and then used to investigate particular cases of ...

Ultrasound Characterization of Plastic Bonded Explosives With Varied Binder Content and Density
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Advanced explosive formulations and methods of production require rapid characterization for both processes and materials. Here, we present results for ultrasound characterization of a plastic bonded explosive (PBX) formulation as a function of binder weight percent and pressing density using through‐transmission sound speed measurements.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Uncertainties in the representation of ice particle size distributions (PSDs) cause inaccuracies in parameterisations of clouds. In this study, observed PSDs from a midlatitude frontal case study are compared with gamma PSDs with the same concentration and ice water content.
