Abstract

Stress wave propagation in solids may be controlled through spatially variable anisotropy. Recently, there have been significant efforts to guide the incident stress waves in desired trajectories in order to protect a sensitive region within the material. Here we present our work on a composite material in which stress waves are guided through smoothly varying elastic anisotropy, while keeping the mass density homogeneous. The axis of anisotropy corresponds to fiber orientation in fiber reinforced composites. In order to guide the stress waves, the axis of anisotropy should smoothly change direction to convey the energy of incident waves.
