Atomistic Nature of Stress in Polymer Networksntropic character of rubber elasticity. That is, the restoring force acting on a piece of stretched rubber is primarily due to its change in entropy, rather than to its change in internal energy. This was established by the work of Kelvin. and Joule. in the middle of the last century. After the natu

Molecular Modeling of the Mechanical Properties of Crosslinked Networksotes the number of starting polymer chains per unit volume has been shown. to greatly underestimate the value of the shear modulus G. Entanglements, which are always present in polymeric systems prior to crosslinking, indeed add a significant contribution to the modulus value given by Eq. 1.
