Shock-induced breaking of the nanowire with the dependence of crystallographic orientation and strain rate.

Figure 2a shows the maximum average potential energy per atom at each strain rate from the statistical results, and the energy increases with the strain rate increasing before the high strain rate of 5.39% ps -1 , but it exhibits a decreasing trend after the strain rate of 5.39% ps -1 , attributing that symmetric shocks are so strong that the shock wave at such high strain rate (>5.39% ps -1 ) has some difficulties in propagating from the two ends to the middle of the nanowire.

In the insensitive area of strain rates (I), the average Y fluctuates within its error, and it behaves as an increasing trend in the transition area of strain rates (II).
