Modeling the Domino Wave Propagation in Contact Mechanics

Adaptive Wave Propagation Modeling

This paper discusses several current attempts to use acoustic and electromagnetic wave propagation for modeling physical phenomena and the role that wavelet analysis is playing in these eeorts. The rst problem involves recent application of wavelets to computational uid dynamics. The second problem involves geophysical modeling of the ocean oor, using acoustic waves, and wavelets have recently ...

Art of Modeling in Contact Mechanics

In this chapter, we will first address general issues of the art and craft of modeling contents, concepts, methodology. Then, we will focus on modeling in contact mechanics, which will give the opportunity to discuss these issues in connection with non-smooth problems. It will be shown that the non-smooth character of the contact laws raises difficulties and specificities at every step of the m...

Wave propagation theory in offshore applications

A frequency-wavenumber-domain formulation is presented in this paper for calculation of the Green's functions and wave propagation modes in a stratified fluid body underlain by a layered viscoelastic soil medium. The Green's functions define the solid and fluid displacements and fluid pressures due to uniform disk loads acting in either the soil or fluid media. The solution is in the frequency ...

Wave Propagation in Micropolar Thermoelastic Diffusion Medium

The present investigation is concerned with the reflection of plane waves from a free surface of a micropolar thermoelastic diffusion half space in the context of coupled theory of thermoelastic diffusion. The amplitude ratios of various reflected waves are obtained in a closed form. The dependence of these amplitude ratios with an angle of propagation as well as other material parameter are sh...
