A computational procedure for analyzing deformation and fracture behavior of solid polymers is developed based on a molecular chain model. In the model, the polymer solid is reprenented by a network of non-linear elastic chains. Van der Waals force and viscous force acting on the chains are taken into account and are approximated to act at the node points of the network. The stiffness equation is derived by employing the principle of virtual work, in which geometrical non-linearity due to large deformation are considered. The chain slippage and the chain session are also taken into consideration. A cellular automaton modeling is introduced to generate the network of polymer chains. The effects of molecularweght distribution and molecular chain session due to ultra-violet degradation are discussed through numerical analysis.
