According to continuum plate theory, the elastic stress waves propagate in plates in the form of Lamb waves due to stress-free surfaces. We transpose the possibility that a parametric pendulum oscillates in the We develop this concept, that can formally applies to any kind of waves, to the case of longitudinal elastic wave. More details may be found elsewhere [5]. Through MD, we can compare the Lamb waves in nanoscale plate to those in continuum plate. The physics of the spatial propagation of monochromatic waves in periodic media is related to the temporal evolution of the parametric oscillators. The bonding strength between the elastomer binder and the particles is approximated by the strength of the solid phase. Key words: Solid State and Materials. Our analysis yields us to study the propagation of of these phonons from the engineering of the periodic structure. The molecules that constitute a solid object have a higher degree of ordination (compared to air, for example) and they also act in transverse motion: if a sound wave goes through a solid object, its molecules will move back and The speed of propagation of sound depends upon the medium features of the medium in which it occurs – elasticity and density, both dependent on the temperature; however, as you probably know it is not dependent on the wave amplitude. Numerical simulations of tension and compression tests on composite materials showing dilatancy The Courant-Friedrich -Lewy criterion states that, for stable computation, the propagation of the elastic wave has to be smaller than one mesh during one time step. In this article, elastic wave propagation and scattering in a solid medium permeated by uniaxially aligned penny-shaped microcracks are studied. All calculations are here in plane strain.
