The Winkler foundation model is often used to analyze the wrinkling of a film/substrate bilayer under compression, and it can be rigorously justified when both the film and substrate are homogeneous and the film is much stiffer than the substrate. We... Read More about Wrinkling of a film/substrate bilayer with periodic material properties: An assessment of the Winkler foundation model.

On the incremental equations in surface elasticity (2024)
Journal Article
Yu, X., & Fu, Y. (in press). On the incremental equations in surface elasticity. Mathematics and Mechanics of Solids, https://doi.org/10.1177/10812865231226183

We derive the incremental equations for a hyperelastic solid that incorporate surface tension effect by assuming that the surface energy is a general function of the surface deformation gradient. The incremental equations take the same simple form as... Read More about On the incremental equations in surface elasticity.

New mountain ridge modes in a film/substrate bilayer (2023)
Journal Article

This article is concerned with the buckling of a film-substrate bilayer in a state of plane strain when it is subjected to a uni-axial compression along its free surface. Previous numerical simulations have indicated that pre-stretching the substrate... Read More about New mountain ridge modes in a film/substrate bilayer.
