Abstract: Shear modulus, shear stress, shear waves speed, travel time of shear waves and work done by a diffusing atom of methane were determined by using thermodynamic relations in which the thermodynamic quantities were obtained from molecular dynamic simulations. The atoms were modeled by Lennard-Jones (LJ) pair potential. The shear modulus, shear stress and shear waves speed decrease as temperature increases and density decreases. The shear waves take longer time to travel at lower densities. The work done by a diffusing atom of methane decreases as the rate of diffusion of atoms increases. Good agreement between prediction from simulation and experimental data is found for shear modulus at T=90.7K.
