Abstract
•FE model captures crack initiation and propagation in Small Punch flat and tube specimens.•Good agreement between experimental and calculated force–displacement curves.•Model captures crack initiation in cold-worked materials with different levels of ductility.•Damage in the material affects force–displacement curves in vicinity of maximal force.
