Hertzian impact: experimental study of the force pulse and resulting stress waves.
Ball impact has long been used as a repeatable source of stress waves in solids. The amplitude and frequency content of the waves are a function of the force-time history, or force pulse, that the ball imposes on the massive body. In this study, Glaser-type conical piezoelectric sensors are used to measure vibrations induced by a ball colliding with a massive plate. These measurements are compa...
متن کاملGaussian solitary waves and compactons in Fermi-Pasta-Ulam lattices with Hertzian potentials.
We consider a class of fully nonlinear Fermi-Pasta-Ulam (FPU) lattices, consisting of a chain of particles coupled by fractional power nonlinearities of order α>1. This class of systems incorporates a classical Hertzian model describing acoustic wave propagation in chains of touching beads in the absence of precompression. We analyse the propagation of localized waves when α is close to unity. ...
متن کاملThe Biological Significanace of Water Structured with Non-hertzian Time Reversed Waves
Contemporary quantum physics has mathematically described and predicted the presence of a new kind of unified energy which underlies conventional transverse electromagnetic (EM) vectors. The concept of a subtle energy underlying EM fields was first introduced by Bohm and Aharonov 1 in describing quantum potentials as an implicate order "embedded in" our normal 3D space. It has recently been pro...
متن کاملInteraction of traveling waves with mass-with-mass defects within a Hertzian chain.
We study the dynamic response of a granular chain of particles with a resonant inclusion (i.e., a particle attached to a harmonic oscillator, or a mass-with-mass defect). We focus on the response of granular chains excited by an impulse, with no static precompression. We find that the presence of the harmonic oscillator can be used to tune the transmitted and reflected energy of a mechanical pu...
متن کاملOn the Existence of Solitary Traveling Waves for Generalized Hertzian Chains
We consider the question of existence of “bell-shaped” (i.e. non-increasing for x > 0 and non-decreasing for x < 0) traveling waves for the strain variable of the generalized Hertzian model describing, in the special case of a p = 3/2 exponent, the dynamics of a granular chain. The proof of existence of such waves is based on the English and Pego [Proceedings of the AMS 133, 1763 (2005)] formul...
