Abstract

A beam of single-layer carbon nanotubes (CNTs) subjected to a shock load in the transverse direction was studied using a chain model with a reduced number of degrees of freedom. The compression shock wave is initiated by a piston moving at a constant speed. Two different scenarios of shock wave propagation and their influence on the structure of the CNT beam depending on the piston velocity were found. At lower speeds, only a faster wave front propagates, which leads to elliptization of the CNT, whereas at higher speeds this is accompanied by a slower wave front of collapse. The evolution of the CNT beam structure in time during compression is studied in detail. The energy absorption rate is estimated as a function of the piston velocity. The results obtained can be useful in the development of new types of elastic shock absorbers.
