Creep is a time‐dependent deformation that occurs when materials are exposed to sustained loads at elevated temperatures. In notched specimens, local stress concentrations exacerbate creep damage, ...

Creeps are characterized as time-dependent permanent deformations that occur under constant stress at elevated temperatures. The material composition determines the onset of creep. For example, steel ...

Measurements of hardness or modulus are not usually helpful in studying time-dependent deformation of a material. It is essential to match load functions in order to make sure that measurements are ...

Member States have shown interest in High Temperature Gas-Cooled Reactors (HTGRs), using graphite as a moderator. If successfully demonstrated, HTGRs will achieve higher thermal efficiencies (45%- 48% ...
