  2. Finite Element Approach for Interaction of Highly Nonlinear Acoustic Waves with Linear Elastic Media

    12 Jan 2011 | Poster | Contributor(s): Devvrath Khatri

      In this work, we developed a threedimensional finite element model (FEM) to study the interaction of highly nonlinear acoustic wave with adjacent linear elastic media. We compare...
