International audience; An attempt is made here to capture numerically slant ductile fracture and its early slant strain precursors via combining a dynamic strain aging (DSA) model with ductile damage models. In recent experimental studies it has bee

International audience; In ductile tearing experiments, a flat crack is often observed to develop normal to the loading direction that subsequently turns into a slant crack. The underlying physical mechanisms are poorly understood. The numerical stra

International audience; High-resolution in situ synchrotron X-ray laminography combined with digital volume correlation (DVC) is used to measure the damage and plastic strain fields ahead of a notch introduced within a 2198 Al-Cu-Li alloy sheet. Sync
