Geometry and physics of wrinkling
WebDec 1, 2014 · Through numerical simulations based on an atomistically informed continuum theory, we understand how strain anisotropy, adhesion and friction govern spontaneous wrinkling. We then propose a strategy to control the location of wrinkles through patterns of weaker adhesion. WebHowever, within bounds set by the physics of wrinkling, it is possible to ro-bustly create by strain a variety of wrinkle network geometries and junction configurations. Graphene is nearly unstrained in the planar regions bounded ... precisely control the network geometry through patterns of weaker graphene-substrate adhesion (Section 4 ...
