What is it about?

Engineering materials have a complex internal microstructure, making it hard to predict how they deform under load. Still, many computer simulations are conducted on very simplified representations of the real structure of engineering materials. In this study, a measured 3D microstructure of a dual phase steel is used as the input for a simulation.

Why is it important?

Crystal plasticity models are able to predict the deformation behavior of metallic materials with high accuracy. To further improve the predictive capabilities of micro-mechanical simulations, it is decisive to focus on the 'weakest link' in the chain of assuptions made to model reality. In this study, the effect of simplifying the microstructure is investigated and it can be assumed that this simplificiation is more detrimental than simplifications in the selected phenomenological constitutive model.

Perspectives

Increasing the measured volume to arrive at statistically representative volume element is the next step.
