Experimental and numerical analysis of the Portevin–Le Chatelier effect in a nickel-base superalloy for turbine disks application

Full-field analysis of damage under complex thermomechanical loading

“…The above set-up yields some high resolution DIC thanks to LASER engraving adapted to both very high temperature and to the targeted spatial resolution. The LASER engraving was previously successfully tested only at 500 • C in [53], and is validated in the present study for the first time up to 900 • C. The macroscopic resolution of displacement is of about 180 µm. Local DIC resolution is of about 60 µm.…”
