Project Short Description
Finite element simulation is a well established tool for the prediction of residual stresses in austenitic steel welds. The mechanical behaviour of the weld material is normally simulated using relatively simple material models, which are calibrated using isothermal tests on material extracted from completed welds. In fact, weld metal is introduced in the molten state and achieves its final mechanical properties via a series of extreme thermo-mechanical load cycles. Its mechanical properties may be strongly directional.
This project seeks to develop more accurate, microstructurally-informed constitutive models for predicting the mechanical behaviour of austenitic weld metal. Representative samples of AISI316L and Inconel 82 weld metal will be manufactured and subjected to isothermal and thermo-mechanical tests in the Universityâs Gleeble thermo-mechanical simulator, accompanied by appropriate microstructural examination using advanced techniques. In parallel, the ABAQUS and ASTER codes will be used to develop improved constitutive models that can predict the observed mechanical behaviour. These will be validated using established international weld benchmarks such as NeT TG4 and TG6.
It is expected that this project will involve extended collaboration with both EDF R & D in Paris, and the Australian Nuclear Science and Technology Centre in Sydney. It is expected that the student will spend some time on secondment in both locations.
