Report
Mechanical performance and life prediction for canister copper

Description
The creep response of the OFP copper at 175 deg C has been studied by uniaxial, multiaxial creep testing, metallography and surface inspections. Surface cracks have been observed in a uniaxial test which has been running for more than 70 000 h (eight years). In a CT-specimen creep cavities have been observed after an exposure of 25 000 h. A purpose-built creep strain model has been implemented into FE analysis to characterize the stress multiaxiality and the stress state of the CT specimen. The results have been applied for life prediction of copper at foreseen levels of stress and temperature at the repository. (orig.)
