Abstract
- Abstract: Nowadays, molecular dynamics simulation has been a significant method in detecting the atomistic-scale kinetics of materials. The objective of this work is to detect the dynamic properties of micro-jet from a nano-grooved aluminium surface by molecular dynamics simulations. For a large range of shock pressure, we investigate the variation of micro-jet mass and morphology. The stacking fault, amorphous state, and release melting during the jetting are all observed, and the effect of release melting on the micro-jet is analyzed. It is found that, the micro-jet mass keeps a linear increase with the piston velocity prior to release melting, the occurrence of release melting can intensify the jetting evidently, and when the velocity of release melting is above a threshold, the jetting mass shows a linear increase with the piston velocity again.
