Query: Computational Models of Material Interfaces for the Study of
  Extracorporeal Shock Wave Therapy   Extracorporeal Shock Wave Therapy (ESWT) is a noninvasive treatment for a
variety of musculoskeletal ailments. A shock wave is generated in water and
then focused using an acoustic lens or reflector so the energy of the wave is
concentrated in a small treatment region where mechanical stimulation enhances
healing. In this work we have computationally investigated shock wave
propagation in ESWT by solving a Lagrangian form of the isentropic Euler
equations in the fluid and linear elasticity in the bone using high-resolution
finite volume methods. We solve a full three-dimensional system of equations
and use adaptive mesh refinement to concentrate grid cells near the propagating
shock. We can model complex bone geometries, the reflection and mode conversion
at interfaces, and the the propagation of the resulting shear stresses
generated within the bone. We discuss the validity of our simplified model and
present results validating this approach.
