Investigations into wave propagation in soft tissue

Abstract

In this article, the authors investigate wave propagation in soft-tissue matter with the aim of understanding the following: i) influence of nonlinear material properties of soft tissue on its mechanical response when subjected to transient loading and ii) mechanical response variation with respect to frequency and amplitude of the loading. To aid these investigations, reduced-order models are constructed taking into account available experimentally determined brain tissue properties and these models are used to study one-dimensional wave propagation in brain tissue fiber bundles. These investigations could help in furthering the understanding of wave phenomena in a skull-brain system subjected to transient loadings. © 2010 Springer-Verlag.
