AI Thread Summary
A large sheet of graphene, when torn, may exhibit different responses to lateral tension depending on the direction of the force applied. Under perpendicular tension, the tear could potentially "unzip," but the behavior may vary based on the strain at the endpoints of the tear. The existing research suggests that the tear could propagate under specific conditions, but definitive data on this behavior is limited. Understanding the mechanics of graphene tears requires further investigation into its material properties and the effects of applied tension. Overall, the question remains partially unanswered due to the complexity of graphene's structural integrity under stress.

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)
