Influence of material inhomogeneity on the mechanical response of a tempered martensite steel
(SAGE Publications, 2017-01-13)
Failure in steel weldments operating at high temperatures often occurs in the heat-affected zone adjacent to the weld. Such failures can be a result of material inhomogeneity within the heat-affected zone and in the case ...
A physically-based creep damage model for effects of different precipitate types
(Elsevier, 2016-10-13)
The development of a new precipitate coarsening continuum damage mechanics (CDM) model to simulate the multi-precipitate strengthening mechanisms present in 9Cr steels under high temperature creep deformation is presented ...
A precipitate evolution-based continuum damage mechanics model of creep behaviour in welded 9Cr steel at high temperature
(SAGE Publications, 2018-04-04)
A multiaxial, physically based, continuum damage mechanics methodology for creep of welded 9Cr steels is presented, incorporating a multiple precipitate-type state variable, which simulates the effects of strain- and ...
Predictions of ICHAZ cyclic thermo-mechanical response in GTAW process for 9Cr steels
(ASME The American Society of Mechanical Engineers, 2019-02-25)
This work is concerned with the development of a modeling framework to predict the effects of tempered–untempered martensite heterogeneity on the thermomechanical performance of welded material. A physically based ...
