Instabilities of thin films on a compliant substrate: Direct numerical simulations from surface wrinkling to global buckling

S Nikravesh, D Ryu, YL Shen - Scientific reports, 2020 - nature.com
For structures consisting of a thin film bonded to a compliant substrate, wrinkling of the thin
film is commonly observed as a result of mechanical instability. Although this surface …
