What is it about?

Investigating the strain partitioning among phases, grains, and subgrains in dual phase steel microstructures with experiments (digital image correlation) and simulations (crystal plasticity).

Why is it important?

The macroscopic deformation behavior of dual phase steels, typically used in structural automotive components, is determined by the interplay of the the microstructural constituents.

Perspectives

As most of the deviations between experiments and simulations can be explained by the missing 3D information in the simulation, going 3D is the next step in this type of analysis.
