A unified viscoplastic model for high temperature low cycle fatigue of service-aged P91 steel
(American Society of Mechanical Engineers, 2014-01-07)
The finite element (FE) implementation of a hyperbolic sine unified cyclic viscoplasticity model is presented. The hyperbolic sine flow rule facilitates the identification of strain-rate independent material parameters for ...
Experimental and numerical characterisation of the cyclic thermo-mechanical behaviour of a high temperature forming tool alloy
(American Society of Mechanical Engineers, 2010-10-05)
This paper describes high temperature cyclic and creep relaxation testing and modeling of a high nickel-chromium material (XN40F) for application to the life prediction of superplastic forming (SPF) tools. An experimental ...
