"Oscillations elastic (also called vibration) in an elastic material, consist in alternately movement around the respective equilibrium positions of the elementary masses"
"The residual stress in a metal doesn't depend on its hardness, {but from the module of elasticity or Young module} and from its chemical composition {(density)}"
"The residual stresses tend to equilibrate themselves in the surface of the material."
"The method discovered analyzes the value of acceleration vibratory generated by an impulse to constant energy with the subsequent reaction elastic (elastic field) from the metal."
Maybe you don't know what the product is your advertising. Oscillations are oscillations.
wave front: A continuous surface drawn through all points in a wave disturbance which have the same phase.
wave length: The distance, measured along the line of propagation, between two wave surfaces in which the phase differs by one complete period. Numerically, the wavelength is equal to the velocity of propagation divided by the wave frequency.
No matter what the mechanism your using for initiation of the wave oscillation, the end result is the same. Propagation of a wavefront(s) through the material. That mechanism can be a hammer blow, a mechanical piston, or a piezoelectic transducer. Sonic, sub sonic, hyper sonic, ultrasonic.. all production a wave front, and with a P wave front it will find it'self in compression or rarefraction.
those wavefronts can take many forms of oscillation depending on the material, temperature etc.
There is longitudinal, transverse, rayleigh, lamb, love, stoneley, sezawa, etc.
V= square root of C ij / p
V is velocity(speed of sound), C = elastic constant, and p = material density ij = directionality of the elastic constants with respect to the wave type and direction of wave travel.
I understood completly what your after. This device your describing is a different twist on an old principle.
