Stress Wave Propagation in Rods and Beams
1958Publisher Summary The problem of the response of structures to dynamic loading is of great importance in a wide variety of technical applications. The loading of a structure can be classified broadly from the viewpoint of time variations. The dynamic loads themselves may be of widely differing kinds depending on the total duration of the pulse, the ...

Wave-propagation in uniaxially-stressed elastic media
pure and applied geophysics, 1972The propagation of waves of small amplitude in an elastic medium, with a particular form of strain-energy function, and subjected to a large homogeneous uniaxial stress, is considered in detail. The main characteristics, including speed and polarisation, of these waves in an unbounded medium are calculated numerically, and the existence and general ...

Radiation Stress in Propagating Elastic Waves
1982 Ultrasonics Symposium, 1982The radiation pressure (actually stress) of a propagating elastic wave is found to depend directly on the acoustic nonlinearity parameters of the solid and the energy density of the wave. The nonlinearity parameters are dependent upon the lattice vibrational properties of the solid and are a measure of the anharmonicity of the interatomic potential ...

Axisymmetric Stress Wave Propagation in Sand
Journal of the Soil Mechanics and Foundations Division, 1970Experiments were conducted in which a rigid cylindrical weight was dropped onto the surface of a bed of sand. Soil stress gages and soil strain gages embedded in the sand were employed to measure the soil response to the impacting weight. These measurements were analyzed to determine the effects of inertia on the soil behavior.

Stress wave propagation in bilayered media
The Journal of the Acoustical Society of America, 1979Integral transform techniques are utilized in order to analyze the propagation of spherical waves in bispherical elastic media. A typical model consists of a cavity of radius r0 located at the center of a spherical material (medium 1) which in turn is embedded in an infinite medium of different properties (medium 2).

Stress wave propagation in composite materials
Structural Engineering and Mechanics, 2001The linear constitutive relations and the failure criteria of composite materials made of thermoviscoelastic solids are presented. The post-failure material behavior is proposed and the dynamic finite element equations are formulated. However, a nonlinear term is kept in the energy equation because it represents the effect of the second law of ...

Propagation of Stress Waves in Metals
1983The application of an external force to a body is, by definition a dynamic process. However, when the rate of change of the applied forces is low, one can consider the process of deformation as a sequence of steps in which the body can be considered in static equilibrium.

Acoustoelastic Lamb wave propagation in biaxially stressed plates
The Journal of the Acoustical Society of America, 2012Acoustoelasticity, or the change in elastic wave speeds with stress, is a well-studied phenomenon for bulk waves. The effect of stress on Lamb waves is not as well understood, although it is clear that anisotropic stresses will produce anisotropy in the Lamb wave dispersion curves.

Propagation of stress waves in inflated sheep lungs
Journal of Applied Physiology, 1989If the lung is an elastic continuum, both longitudinal and transverse stress waves should be propagated in the medium with distinct velocities. In five isolated sheep lungs, we investigated the propagation of stress waves. The lungs were degassed and then inflated to a constant transpulmonary pressure (Ptp).

Equipment for ''Watching'' Propagating Stress Waves
Review of Scientific Instruments, 1959The propagation of stress waves generated by impact may be ``watched'' photoelastically with the use of the simple experimental arrangement described herein. In addition to providing control over the observed progress of the wave, the apparatus makes possible photography of the wave with conventional cameras.
