Direct molecular dynamics (MD) simulations of the fracture of a simple liquid are performed. The kinetics of void nucleation and growth are obtained from MD simulations with a Lennard-Jones interatomic potential. A model of fracture based on void nucleation and growth kinetics is proposed. Analysis of fracture kinetics and an estimation of spall strength arc presented. The results of the model arc in good agreement with direct MD simulations and experimental data (for hexane).
