You have included non linear effects (NLGEOM) but chose a singularity pertaining to brittle fracture (quarter point elements). The simulation is incorrect.
How do you adjust the local seed number for the circular contour to get the singularity at the center of crack tip? I cannot get triangular elements centered on the crack tip

What are your units of Young’s modulus ?
Why are you quite silent throughout the video.?
where is the crack??....
Invisible cracks
