ABSTRACT The elastic constants C ik of solids are related to the amplitude of the strain fluctuations which can be simulated atomistically, thus offering a possibility of determining the C ik values of the solid of interest based on a proposed atomistic arrangement and a given interaction between the atoms. We show that the approach is practical by calculating the elastic constants of crystalline (orthorhombic) polyethylene, crystalline (monoclinic) isotactic polypropylene, and glassy bisphenol‐A‐polycarbonate.
