2007:12 Development of a constitutive model for the plastic deformation and creep of copper and its use in the estimate of the creep life of the copper canister
these have all involved very short duration tests at relatively high stresses. Reported creep tests on oxygen free (OF) copper have demonstrated that copper can have extremely low creep ductility. However ... basis for a discussion on the possibility of brittle creep fracture of the copper canister during long term storage of nuclear waste in this project. Results Reasonable assumptions on the temperature dependence...
