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 ...
The effect of inclusions on the high‐temperature low‐cycle fatigue performance of cast MarBN: Experimental characterisation and computational modelling
(Wiley, 2018-06-15)
The presence of inclusions is a known source of crack initiation and component failure in cast materials. In this work, the role of inclusions is investigated via a combined program of high-temperature low-cycle fatigue ...
