Simulation software DIGIMU®

developmentindustrialfor the aerospace industry

The aim of DIGIMU® is to propose an industrial solution for simulating microstructure changes, at the mesoscopic scale and on Representative Elementary Volumes (REVs), during metal forming processes. Software derived from Research DIGIMU® is the result of research projects conducted for more than ten years at the CEMEF (Material Forming Center) in collaboration with many industrial stakeholders from the metallurgy, aeronautics and nuclear sectors. The two pillars of DIGIMU® software development are the extensive experimental work and the constant improvement of existing numerical methods, which allow CEMEF to be at the forefront of world research in the field. The full-field approach The full-field approach proposed by DIGIMU® has two main objectives: To simulate local and heterogeneous phenomena that are undetectable to larger order models To improve medium-field models used for industrial part-scale simulations DIGIMU® generates digital polycrystalline microstructures representative of the material's heterogeneities (compliance with the topological characteristics of the microstructure). The boundary conditions applied to the REV are representative of that experienced by a material point at the macroscopic scale (thermomechanical cycle of the considered point). Based on a Finite Elements formulation, the various physical phenomena involved during metal forming processes are simulated (recrystallization, grain growth, Zener pinning due to second phase particles, etc.).
