Surface instability of compliant film/substrate bilayers has raised considerable interests due to its broad applications such as wrinkle-driven surface renewal and antifouling, shape-morphing for camouflaging skins, and micro/nano-scale surface patterning control. However, it is still a challenge to precisely predict and continuously trace secondary bifurcation transitions in the nonlinear post-buckling region. Fundamental understanding and quantitative prediction of morphological evolution and pattern selection are, in fact, crucial for the effective use of wrinkling as a tool for morphological design.
