Modelling of thermo-mechanical and irradiation behavior of metallic and oxide fuels for sodium fast reactors
… and Clad Mechanical Analysis and (6) Transient Creep- Fracture Model for the clad. Given the fuel pin geometry, composition and irradiation history, FEAST can analyze fuel and cladding thermo-mechanical behavior at both steady state and design-basis accident scenarios. FEAST was written in …

EXPERIMENTAL STUDIES OF THE MECHANICAL BEHAVIOR OF A PVA DUAL-CROSSLINK HYDROGEL
… tip, which leads to high stress that causes the fracture of the material. Thirdly, we developed a predictive fracture criterion for this material. We loaded the specimen with an edge crack to fracture under two loading conditions: constant applied stress (creep) and constant stretch rate. The …

Chemomechanical modeling of hydrogen-induced degradation at high temperatures
… which can ultimately grow and can lead to fracture. The design of steel equipment against HTHA is primarily based on the use of the Nelson curves published by the American Petroleum Institute (API) which are empirical and do not account for the underlying failure mechanisms, the material …

Surface degradation and creep of Inconel 617 and Haynes 230 at high temperatures
… effects on the materials and the relevant creep deformation behavior is critical for the design and long-term operation of the HTGR. Inconel 617 (alloy 617) and Haynes 230 (alloy 230) are considered as primary candidate materials for serving in the HTGR, due to their exceptional combination …
