"Visualization and modeling of fracture at the microscale"
Funding: European Union, Horizon 2020 Programme (Grant Agreement 659575)
Project period: 2015 – 2016
Principal Investigators: Dr. Arnaud Weck (arnaud.weck(AT)imdea.org)
MicroFrac aims at providing a significant contribution towards our understanding of fracture at the microscale through a combination of state-of-the-art experiments and models. Micro voids will be introduced in metallic single crystals and their growth will be followed in-situ at high resolution. The effects of void size and crystal orientation will be investigated and the results will be used to validate dislocation dynamics and crystal plasticity models of void growth.
The expected outcomes of the project will be new experimental evidence of fracture at the microscale and the creation of an improved crystal plasticity model that can take into account size effects during void growth to improve the predictions of ductile fracture by nucleation, growth and coalescence of voids. New material designs with improved fracture resistance will also be proposed.
