A New Model for the Dynamic Behavior of Elastomeric Materials.
Abstract
A mathematical model describing the dynamic behavior of rubber or elastomeric materials was developed. It is based on Flory's concept of the rotational isomeric state model of polymer chains. With a unit step strain applied to the material, each polymer chain is assumed to go from an unrelaxed initial configuration to a fully relaxed equilibrium state at a rate described by a non-linear first-order differential equation. The differential equation is derived by assuming that the relaxation rate is proportional to a probability function, namely, the probability that the elastic and thermal energy present in the chain is greater than or equal to a critical value.
