Abstract

We study the interaction of one-dimensional acoustic solutions with an inhomogeneous elastic medium containing a spherical void. We investigate the influence of the in homogeneity on the reflection of incident acoustic solutions using a hybrid model consisting of finite-element and discrete element methods. The reflection of incident acoustic solutions and the time of flights of reflections are found to be dependent upon the changes in the contact interaction between the last particle and the inhomogeneous medium. Furthermore, the time of flights of the reflected acoustic solutions are sensitive to the size and the location of a void.
