Divider Telephone Cord Delam

divider-telephone-cord-delam

A full-width section divider modeled on thin-film delamination buckling, a compressive-stress film debonding from its substrate and popping upward into the real 'telephone cord' morphology: a roughly constant-width ridge that telescopes side to side as its failure front advances and periodically re-forks, never a straight blister.
