Stress Wave Propagation in Elastic-elastic and Elastic-viscoelastic Bilaminates

In the present study normal plate-impact experiments are conducted to investigate the propagation of acceleration waves in 2-D layered material systems. The objective of these experiments is to understand the role of material architecture and material inelasticity in controlling precursor decay and late-time dispersion of acceleration waves in elastic-elastic and elasticviscoelastic laminates. ...

Elastic wave propagation along DNA

It is shown that information transmission inside a cell can occur by means of mechanical waves transmitted through DNA. The propagation of the waves is strongly dependent on the shape of the DNA thus proteins that change the shape of DNA can alter signal transmission. The overall effect is a method of signal processing by DNA binding proteins that creates a ”cellular communications network”. Th...

Wave Propagation in 3 - D

The elastic wave equation in spherical coordinates is solved on a spherical section by a Chebyshev spectral method. In the presented algorithm the singularities in the governing equations are avoided by centering the physical domain around the equator. The highly accurate pseudo-spectral (PS) derivative operators reduce the required grid size compared to nite-diierence (FD) algorithms. The non-...

Wave Propagation in a Layer of Binary Mixture of Elastic Solids

This paper concentrates on the propagation of waves in a layer of binary mixture of elastic solids subjected to stress free boundaries. Secular equations for the layer corresponding to symmetric and antisymmetric wave modes are derived in completely separate terms. The amplitudes of displacement components and specific loss for both symmetric and antisymmetric modes are obtained. The effect of ...
