Cyclic viscoplasticity testing and modelling of a service-aged P91 steel
Farragher, Tadhg P.; Leen, Sean B. (American Society of Mechanical Engineers, 2014-04-16)A service-aged P91 steel was used to perform an experimental program of cyclic mechanical testing in the temperature range of 400 °C–600 °C, under isothermal conditions, using both saw-tooth and dwell (inclusion of a ... -
Development of life assessment procedures for power plant headers operated under flexible loading scenarios
Farragher, Tadhg P.; Leen, Sean B. (Elsevier ScienceDirect, 2013-12-22)A finite element methodology for thermo-mechanical fatigue analysis of a subcritical power plant outlet header under realistic loading conditions is presented. The methodology consists of (i) a transient heat transfer ... -
High temperature, low cycle fatigue characterisation of P91 weld and heat affected zone material
Farragher, Tadhg P.; Leen, Sean B. (American Society of Mechanical Engineers, 2014-01-08)The high temperature low cycle fatigue behavior of P91 weld metal (WM) and weld joints (cross-weld) is presented. Strain-controlled tests have been carried out at 400 °C and 500 °C. The cyclic behavior of the weld material ...
