Surface instabilities in bilayer systems composed of a thin,hard film bonded to a thick,soft substrate have been studied extensively in recent years both experimentally and theoretically.Some different types of surface instabilities have been characterized by tuning the ratio of parameters involved layers such as the stiffness ratio and the thickness ratio: creases,wrinkles,and folds.The formation of the surface patterns has mainly focused on two-dimensional plane-strain models under uniaxial compression.When subjected to biaxial compression,a thin film can buckle into different patterns such as checkerboard,hexagonal,herringbone,triangular,and labyrinth patterns.Here,we explore the morphing patterns of bilayer elastomers under biaxial compression.Through combining experiments and computations,we especially focus on understanding how anisotropic biaxial loads govern the morphing patterns.We then propose a strategy to control them by the anisotropic loads.
