• : graphyne; in silico studies; stress wave propagation; supersonic-velocity impact; Introduction Owing to its versatile flexibility, carbon is able to form three different hybridization states namely sp, sp2 and sp3, which yields many kinds of carbon allotropes. Graphite and diamond are the two common

• across the nanosheet prior to bond breakage. Since the stress distribution is largely determined by the propagation of elastic stress, it is of great importance to compare the stress wave propagation velocity in the examined GYs. In a GY with higher elastic wave propagation velocity, the momentum tends

• morphology will alter the deformation mechanism of GY under impact. Considering the different elastic stress wave propagation velocities, it is crucial to examine how the GYs will performance under different impact velocity amplitudes. For this purpose, we consider the deformation of an α-GY nanosheet under
