Contact Transmission of Wave Motion between Two Solids with an Initial Gap

چکیده
AWH-Tk paper tre8ts the bramission of wave motion from one solid to rnotber when the bodies ue hitially spurted by I: small pp. If a pulse of elastic waves strikes the surface of one of the solids and the rmplitude of the pulw ir iaqe enough, I& solids can come into con&t and interact locally. The dynamic interaction is treated using Coulomb’s friction law, and a method is presented for finding the slip ad stick zones in the contact region when the incidence angle of the pulse is subcritii. Unusual results are encountered for large friction coefficients.

Reflection and Transmission at the Boundary of Two Couple Stress Generalized Thermoelastic Solids
In this paper the reflection and transmission at a plane interface between two different couple stress generalized thermoelastic solid half spaces in context of Loard-Shulman(LS)[1967] and Green-Lindsay(GL)[1972] theories in welded contact has been investigated. Amplitude ratios of various reflected and transmitted waves are obtained due to incidence of a set of coupled longitudinal waves and c...

Reflection and transmission of plane waves between two initially stressed thermoelastic half-spaces with orthotropic type of anisotropy is studied. Incidence of a SV-type wave from the lower half-space is considered and the amplitude ratios of the reflected and transmitted SV-wave, P-wave and thermal wave are obtained by using appropriate boundary conditions. Numerical computation for a particu...

متن کاملAn Adaptive Physics-Based Method for the Solution of One-Dimensional Wave Motion Problems
In this paper, an adaptive physics-based method is developed for solving wave motion problems in one dimension (i.e., wave propagation in strings, rods and beams). The solution of the problem includes two main parts. In the first part, after discretization of the domain, a physics-based method is developed considering the conservation of mass and the balance of momentum. In the second part, ada...
