Pond T. J., . Creep behaviour of rubbers subjected to repeated loadings. pp. 93-106. ISSN 0127-7065
Abstract
The creep behaviour of various rubbers has been studied when subjected to repeated loading conditions (cyclic creep and compared to the creep behaviour under equivalent constant load conditions. It has been found that the repeated loading of strain crystallising rubbers under high stress levels can produce a substantial enhancement of creep rates over that observed in the static loading condition. The presence of crystallisation during stressing is thought to induce high stresses in the rubber network near the boundary region of the crystal sites and that these high stresses lead predominantly to the breakage of crosslinks. It appears from swelling and set measurements that crosslink breakage is responsible for approximately half of the total cyclic creep with visco-elastic effects accounting for the remainder.
