Creep-fatigue interactions in a polycrystalline structural material under typical high-temperature power plant operating conditions
Markian Petkov, Marc Chevalier, David Dean +1
A micromechanical model at the microscale within a crystal plasticity self-consistent model, is used to analyse loading histories in Type 316H stainless steel, common to structural…

Evaluation of local stress state due to grain-boundary sliding during creep within a crystal plasticity finite element multi-scale framework
Markian Petkov, Elsiddig Elmukashfi, Edmund Tarleton +1
Previous studies demonstrate that grain-boundary sliding could accelerate creep rate and give rise to large internal stresses that can lead to damage development, e.g. formation of…
