Speeds of surface elastic wave propagation over the human chest along and across the ribs are found. Ten healthy male volunteers have participated in the experiment. Vibrations of a striker-vibrator and a light accelerometer in contact with the chest have been detected using a specially designed ...
Initial shock wave speed was estimated at 640 mph. FromWashington Post Finally, because the authors recorded waves travelling in all directions across their array, they were able to account for the contribution of anisotropy to wave speed. FromNature Fast wave speed anomalies appear in areas with ...
The first-order nonlinear correction to this speed for waves with a reasonable amplitude of 10 m is about 0.1 m [s.sup.-1] and thus on the order of 1/3 of the linear wave speed. The impact of the cubic nonlinearity adds approximately 0.03 m [s.sup.-1], that is, another 10% of...

This paper is concerned with the conditions which must be imposed on the strain-energy function for an isotropic compressible elastic material in order to ensure that, when the material is subjected to a static pure homogeneous deformation, plane sinusoidal waves of infinitesimal amplitude propagate in...
As we know, a wave is a disturbance that propagates from its point of origin. For example, when you throw a rock into a pond, the ripples or water waves move on the surface of the water in the outward direction from where you dropped the rock. Wave speed is the speed at which the...
A method is considered for determining the distance between two wedges and the speed of longitudinal ultrasonic waves in a test object when measuring the profile of the surface of pipelines under the bead of a weld. The method makes it possible to reduce the error in determining the profile of...
Tornado - Wind Speed, Vortex, Destruction: Fully developed tornadoes contain distinct regions of airflow. As is shown in the figure, the central axis of circulation is within the core region, a roughly cylindrical area of lower atmospheric pressure that
Wave breaking at the surface of the ocean entrains bubbles, significantly modifying the phase speed and attenuation of acoustic waves propagating through the resulting two-phase medium. An autonomous buoy system was developed that directly measuressound speed at 3.33, 5, and 10 kHz at seven depths...
