An improved unified viscoplastic model for strain-rate sensitivity in high temperature fatigue
(Elsevier ScienceDirect, 2013-11-21)
An improved unified cyclic viscoplastic material model for high temperature fatigue of P91 steel is presented. The primary enhancement over existing models is in relation to strain-rate independence of parameters, for ...
A multi-axial cyclic viscoplasticity model for high temperature fatigue of P91 steel
(Maney Online, 2014)
This paper presents a novel multiaxial, cyclic viscoplasticity material model for high temperature low cycle fatigue of P91 power plant steel. The model incorporates mechanisms-based variable strain-rate sensitivity and ...
