Crack-tip fields for materials with exponential-law-creep behavior at high stress: Final report
Technical Report
·
OSTI ID:6606367
This work focused on elastic-viscoplastic analyses of cracks under creep conditions, with particular emphasis on the influence of the assumed stress dependence on the creep strain-rate. At high stress levels the creep strain-rate for many structural materials varies as the exponential of stress while at low stress levels it varies as stress to some power. The complete stress dependence is given in terms of the known hyperbolic-sine creep law.
