Micro Abstract:
A computational framework is introduced to validate simulations at the microscale. A specimen made of cast iron is imaged via synchrotron laminography during a tensile test. The region of interest is analyzed by Digital Volume Correlation (DVC) to measure kinematic fields. Finite Element simulations, which account for the studied material microstructure, are driven by Dirichlet boundary conditions extracted from DVC measurements. Gray level residuals are assessed for validation purposes.
