Localized ridge wrinkling of stiff films on compliant substrates
Wrinkling of thin stiff films on thick compliant elastomeric substrates subject to plane strain compression is considered for cases in which the substrate is pre-stretched prior to film attachment. Advanced wrinkling modes are investigated that evolve as the systems are compressed beyond the onset of the primary sinusoidal wrinkling mode. If the substrate pre-stretch is greater than about 40%, ...

متن کاملConcomitant wrinkling and buckle-delamination of elastic thin films on compliant substrates
Compressing a thin elastic film attached to a thick compliant substrate can lead to buckling instability. Two commonly observed buckling modes, buckle-delamination and wrinkling, have each been analyzed separately in previous studies. Recent experiments have observed that the two modes can co-exist and co-evolve. In this paper, by analytical and finite element methods, we present a study on con...
متن کاملPath-guided wrinkling of nanoscale metal films.
Surface wrinkling instability is typically caused by compressive stresses in layered systems. In a bilayer system with a stiff surface layer on a drastically more compliant substrate, spontaneous wrinkle patterns emerge as a result of the wrinkling instability. The wrinkle patterns can be controlled to form ordered surface structures, offering an unconventional method for microfabrication. [ 1–...
متن کاملBuckling modes of elastic thin films on elastic substrates
Two buckling modes have been observed in thin films: buckle delamination and wrinkling. This letter identifies the conditions for selecting the favored buckling modes for elastic films on elastic substrates. Transition from one buckling mode to another is predicted as the stiffness ratio between the substrate and the film or is predicted for variation of the stiffness ratio between the substrat...
