The structure-sensitive parameter 7 which describes the Influence of uniaxial stress on the rate of molecular breakage can, according to recent calculations, be related to the elastic modulus, E(e), of the oriented sample.

β¦ Synopsis
The times to failure for several materials, both metals and plastics, are compared for static and cyclic loadings. Their similarity leads to the conclusion that the fracture is caused by the same elementary processes, with their thermofluctuatinn nature being described by the Zhurkov formula.

Physically based, rational, constitutive laws are developed by analysis or synthesis: the second represents the maturity of deformation and fracture science. The basic processes are thermally activated discrete steps, each controlled by the elementary rate constant derived rigorously by rate theory
