Abstract

The stress relaxation response and the changes in lateral dimension brought by the relaxation for epoxy and glassy carbonate subjected to both tension and compression were studied. The relaxation modulus, volume or Poisson's ratio were time dependent. The rate of volume change increased in both tension and compression as the absolute magnitude of applied strain increased and a time dependent densification was observed for the two conditions after an applied initial hydrostatic stress.
