Stress Wave Propagation in Two-dimensional Buckyball Lattice.

ABSTRACT: Orderly arrayed granular crystals exhibit extraordinary capability to tune stress wave propagation. Granular system of higher dimension renders many more stress wave patterns, showing its great potential for physical and engineering applications. At nanoscale, one-dimensionally arranged buckyball (C₆₀) system has shown the ability to support solitary wave. In this paper, stress wave behaviors of two-dimensional buckyball (C₆₀) lattice are investigated based on square close packing and hexagonal close packing. We show that the square close packed system supports highly directional Nesterenko solitary waves along initially excited chains and hexagonal close packed system tends to distribute the impulse and dissipates impact exponentially.
