Micro Abstract:
Recent techniques of 3D synchrotron imaging allow to fill the gap between several fields of experimental damage mechanics. The present work combines local crystallographic characterisation and the related plasticity mechanisms to observations and quantitative measurements of the three stages of ductile fracture, applied on aluminium. Phase and diffraction contrast tomography are used as input for modelling to better understand the local stress and deformation state governing damage.
