Abstract: We numerically study uncompressed granular crystals excited by sinusoidal signals at 1–100 kHz. A simple system such as two beads in a line reveals that for a fixed driven frequency, incident signals can be transmitted or… read more here.

Abstract: In this paper, a pre-compressed one-dimensional granular crystal model is studied. The bright analytic single and multiple solitary wave solutions in more general forms than those obtained the KdV system in the previous studies are… read more here.
