Controlling wave propagation in solids using spatially variable elastic anisotropy

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