Experimental Examination of the Statistical Theory
Leslie R. G. Treloar · 2005
Abstract IN the last chapter we saw that the statistical network theory leads to an expression for the work of deformation in a pure homogeneous strain of the most general type (eqn (4.9)), and to corresponding general stress-strain relations (eqns (4.18)), which involve only a single material constant or modulus, which is related to the degree of cross-linking or number of chains per unit volume of the network (eqn 4.9b)). Attempts to verify the theory by comparison with the actual properties of rubbers have been concerned both with the form of the stress-strain relations, and with the comparison of the measured value of the modulus with that deried from chemical estimates of the degree of cross-linking.
