If one had a large sheet of graphene (as in square meters--but not necessarily a monolayer sheet) which was then puctured/torn by a blade, how would the tear react to lateral tension parallel and perpendicular to the tear? Would it "unzip" easily under perpendicular tension, or would the endpoints of the tear bear strain before giving way further?
(If this is a totally unanswerable question due to lack of data, I understand. Thanks anyway! xD)
