polycrystals

Structural Integrity and MEchanical Design (SIMED) group is seeking a 17-month full-time Postdoctoral Researcher (or Associate Researcher, not holding a PhD) in Computational Fracture Mechanics. The successful applicant will work at the Polytechnic Engineering and Architecture Department (DPIA) of the University of Udine, under Dr Enrico Salvati’s supervision.

I would like to share an article that was recently published in CMAME.

It is about MicroStructPy, a very flexible microstructure generator able to represent various statistics for microstructures with multiple phases. It works in 2D and 3D and you can provide, for each phase, grain size distributions, volume fraction, elongation and orientation distribution for elongated grains, etc.
