Invited Lecture


 A Unified Interpretation of Stress in Molecular Systems

Abstract. At the molecular level there are atoms and forces, whereas continuum theories deal with fields and stress. To connect between these models of reality, it is necessary to obtain expressions for continuum variables, such as stress, at the molecular level. To date many different expressions have been proposed and some confusion exists in the literature as to which is "correct". We show that a unified framework, based on the work of Irving and Kirkwood and later Noll, can be established from which all other expressions can be derived. The theoretical framework as well as numerical results will be presented.
