Bending Solid Elastic Waves with Arbitrary Angles by Bricks

Author:
Hu, Jin   Lu, Xiang Yang  


Journal:
Applied Mechanics and Materials


Issue Date:
2012


Abstract(summary):

Transformation method provides an efficient way to control wave propagation by materials. Recently, this method has been extended to control elastic waves in solids in case of high frequency or small material gradient. An important device in practice, elastodynamic beam bender with isotropic materials, can be designed by this method. In this paper, we will explore some characteristics of the isotropic elastodynamic beam bender and show that it can be used as bricks to guide the solid elastic beam to arbitrary angles, providing more flexibility in engineering practices. Examples are conceived and validated by numerical simulations.
