Abstract:

The concept of combining the latest finite element (FE) and discrete element (DE) multiscale numerical technologies for modelling of the tool/workpiece interface during high shear processing is described. The potential of FE tools and techniques merged with DE based transient dynamics is highlighted. The described numerical approach combines the DE transient dynamics used for meso- level modelling with FE analysis used for macro- level simulation. The transfer processes are described by the system of diffusion and motion equations including contact detection and interaction solutions for particles integrated in time. As an example of the application, modelling of the tool/workpiece interface including heat generation during friction stir welding (FSW) is considered.
