Abstract

Z-mat software is used to implement the multiaxial form of the Chaboche unified viscoplastic constitutive equations into the Abaqus finite element (FE) code. Complex transient stress fields within a grade P91 steel notched bar specimen are investigated in detail for different thermomechanical fatigue (TMF) loading conditions. The results of this work can be used to determine suitable test conditions for notched specimens by providing predictions of the stress-strain history local to the notch. In future, such tests will be used along with the FE analyses to develop and validate multiaxial TMF lifing models.
