Development of unified viscoplastic constitutive equations to model micro-structure and damage evolution in hot/warm metal forming processes.
Some examples include:
(i) phase transformation in hot-stamping with cold-die quenching;
(ii) grain growth in superplastic forming;
(iii) age precipitation hardening in creep-age-forming;
(iv) recrystallisation, grain size and damage evolution in hot rolling, etc…
Development of Evolutionary Algorithms (EA)-Based optimization techniques for the determination of physically-based unified constitutive equations from experimental data.
