The development of new materials with advanced mechanical properties has been a major mission and contribution of material scientist in combating global climate change. Understanding and controlling the mechanical properties are of critical importance, which is also closely related to the development of material models and theories. The mechanical properties of metallic materials are affected by both intrinsic and extrinsic factors. The research group Macroscopic Modelling provides reliable concepts and solutions to simulate and predict the macroscopic mechanical behavior of steels and other alloys in various loading scenarios.
A variety of approaches, including constitutive plasticity model, damage mechanics and fracture mechanics, are applied to describe the plastic deformation, localization, ductile, cleavage and fatigue failure in metallic materials. The developments of advanced materials, constitutive models and failure criteria to improve the numerical prediction of materials properties and component performance have been the major research activities in the Macroscopic Modelling group. On the other hand, multiscale numerical simulation approaches are also used to establish the link between macroscopic mechanical properties and microstructural features of different materials.
