Assignment

"Constitutive modelling for metallic materials"

Because of the growing environmental problems and energy issues, a number of researches have been carried out on the lightest metal magnesium. However magnesium alloys show poor workability and of limited use when compared with other existing structural materials. That's why considerable efforts for improvement of their workability have been made by applying the control of crystallographic texture, grain refinement and so on.

The reason for this poor workability of magnesium alloys is strongly linked to its hexagonal close-packed crystal structure. So the numerical analysis considering crystal scale (meso-scale) phenomena is very useful for the prediction of anisotropic deformation behavior and the understanding of deformation mechanism.

This research focuses on the constitutive modeling for mechanical behavior of magnesium alloys considering meso-scale phenomena.
