Mechanism for controlling buckling wrinkles by curved cracks on hard-nano-film/soft-matter-substrate
Source abstract
Abstract
Abstract A study on the surface wrinkling of thin stiff film/soft substrate by patterning the film/substrate with curved cracks is introduced in the present work. From abundant experimental consequences, it is revealed that on the concave side of the curved crack the wrinkling is suppressed, and on the convex side the wrinkling is induced. Based on the fundamental theory of elastic mechanics, the analysis reveals that on the concave side the compressive stress is released and on the convex side the compressive stress is concentrated, and this analysis could offer explanation on the suppression and induction effects of the curvature. Meanwhile, from our carefully designed experiment, we find when the curvature is sufficiently small, curvature of the curves cannot afford to suppress the wrinkling even at the concave side.
