Stress wave propagation in A1 single crystals

Czechoslovak Journal of Physics, 1977
Transmitted wave profiles are presented for A1 single crystals that were loaded along crystallographic directions [100], [110] and [111] by a stress wave of the amplitude 1·85 GPa. The experiments were carried out with the Hopkinson Split Bar Technique. The observed wave profiles strongly depend on the specimen length.

Stress wave propagation in Boron-Nitride nanotubes

Computational Materials Science, 2017
Abstract The propagation of axial stress waves in Boron-Nitride nanotubes of different chirality and length under adiabatic conditions has been studied using molecular dynamics (MD) simulations. The velocities of the axial stress waves are found using three methods - (i) direct MD simulations, (ii) harmonic approximation of the nanotubes, and (iii ...

Stress wave propagation in rectangular bars

International Journal of Solids and Structures, 1969
Abstract The method of collocation is used to obtain dispersion curves for wave propagation in infinite rectangular bars. It is found to give accurate results, over a limited range of wave numbers, for the first two branches of the dispersion curves for the various modes of propagation.

Wave propagation in initially-stressed elastic rods

Journal of Sound and Vibration, 2019
Abstract This paper presents a study of incremental wave motion in elastic media with initial stress. Alternative formulations of the governing equations are examined as independent developments as well as special cases of a general theory in which the strain energy function is written in terms of deformation and initial stress.

Stress-wave propagation in Al2O3-epoxy mixtures

Journal of Applied Physics, 1978
One-dimensional shock loading, attenuation, and recompression data from gas-gun experiments on mechanical mixtures of alumina powder and epoxy were used to develop model parameters for stress-wave propagation. Specimens with 0.42, 0.34, and 0.20 volume fractions of alumina were investigated.

Propagation of Stress Waves in Liquids

Nature, 1964
THE underlying assumption implicit in work concerned with the propagation of stress waves in liquids is that any pressure disturbance originating at some point in the liquid travels unchanged in form with a velocity c = √(dp/dρ), which is independent of the density.

Stress Wave Propagation in Slender Bars

1997
With the availability of today’s advanced technology, experimental data are often available in various types and forms. It is important to examine as many sources of such data as is reasonable in formulating a particle model. In this chapter, we will show how to incorporate available stress and strain measurements for slender aluminum bars in order to ...

Stress Wave Propagation in an RTV Rubber

Transactions of the Society of Rheology, 1976
The response of a “rubbery” polymer, Dow Corning Silastic J Mold Making Silicone Rubber, to high-amplitude, short-duration loading is studied using acoustic waves and high-amplitude stress waves. The acoustic experiments measured the phase velocity of a 1 MHz wave over a temperature range of −30°C to +65°C.

Numerical methods for nonlinear stress wave propagation

Proceedings of the SIGNUM meeting on Software for partial differential equations -, 1975
The partial differential equations characterizing stress wave propagation problems include conservation of volume, mass, momentum, and energy plus the constitutive relations for the materials involved. Generally these constitutive relations are nonlinear and numerical methods are required for solutions in various coordinate systems and spatial ...

Propagation of stress waves in rubber rods

Journal of Polymer Science, 1957
AbstractThe propagation of longitudinal, torsional, and flexural waves in rubber rods was studied by a moving probe method. Conditions and materials were used for which the attenuation was sufficient to eliminate standing waves. Velocity and attenuation data were obtained for the different wave types over the frequency range 1 to 8 kc.
