E-mail: shlee@ks.ac.krReceived June 8, 2012, Accepted June 25, 2012Pressure tensors at the planar surface of liquid-vapor argon are evaluated from the virial theorem, Irving-Kirkwood, and Harasima versions using a test-area molecular dynamics simulation method through a Lennard-Jones intermolecular potential at two temperatures. We found that the normal and transverse components ofthe pressure tensor, p
