N2 - As a result of the flexibility provided by the transformation elastodynamics, the impedance-matched condition exists for both S and P waves in perpendicularly incident cases in isotropic materials, thus the isotropic elastic wave beam bender can be designed. In this paper, we explore some characteristics of this bender and show that by assembling the bender units a solid elastic beam can be guided to an arbitrary path, which will provide convenience in engineering practices. Examples are conceived and validated by numerical simulations.
