Discontinuity in the in-plane to out-of-plane transition of Kirigami

Abstract

Recently, we have shown that kirigami's high extensibility emerges as a result of the transition in its deformation modes and that the transition observed through the force-elongation curve can be discontinuous. Using our previous model, we recover the discontinuous transition, deriving an expression that characterizes the force discontinuity at the point of transition. We further show that this expression well accounts for our experimental results.
