Paper Abstract

We have successfully designed a linear two-way one-dimensional acoustic diode by a combined use of the heterogeneity of functionally graded material and the finite size of the practical phononic device. In this study, we further explore the large deformation characteristics of hyperelastic soft material. We first showed through numerical simulation that, the pre-deformation can be well used to tune the working performance of the soft acoustic diode by changing the direction of the unidirectional wave propagation. Experiments are also conducted to validate the theoretical predictions.
