Abstract
A model of local breakdown is proposed for calculating the life span of load-carrying technical-grade rubber parts, based on the thermodynamics of irreversible processes and on the entropy criterion of breakdown. The entropy hypothesis has been proved experimentally, and the numerical value of the critical specific entropy has been obtained for grade IRP-1347 rubber, this value being constant for a given material.
