Film structures have been widely used in flexible electronics, material science, metrology, biomedical engineering and aerospace engineering. When a thin film is loaded with compressive stresses, buckling accompanied by wrinkles is likely to occur under constrained boundaries. Many previous studies have focused on the wrinkling mechanism of a free-standing film or a film–substrate structure, in which compressive stresses in the film are caused by the mismatch between the film and the imposed constrains from its boundaries or the substrate. Instead of using the homogeneous substrate, here we propose a film-lattice structure consisting of a thin film bonded to a bottom-supported lattice. By controlling the buckling of the lattice structure, a distribution of compressive loads can be applied to the film, finally resulting in the generation of periodic wrinkles. Physical mechanism on the buckling-driven wrinkle pattern is investigated with the increasing loading. Dimensionless parameters and their effect on governing the wrinkling mode are also analyzed numerically. The exploration on features of the wrinkles on the film shows that the wrinkle pattern can be controlled by designing the lattice substrate. Our works could help understand the wrinkling caused by the buckling of a complex substrate and guide the harnessing of wrinkles in the design of new materials and structures.

薄膜结构已广泛用于柔性电子，材料科学，计量学，生物医学工程和航空航天工程。当薄膜受到压缩应力时，在受限边界下可能会发生屈曲并伴有皱纹。以前的许多研究都集中在独立式膜或膜-基底结构的起皱机理上，其中膜中的压缩应力是由于膜之间的不匹配以及从其边界或基底施加的约束而引起的。代替使用均质基板，我们在此提出了一种薄膜格结构，该结构由结合到底部支撑的晶格上的薄膜组成。通过控制晶格结构的屈曲，可以将压缩载荷分布应用于薄膜，最终导致周期性皱纹的产生。随着载荷的增加，研究了屈曲驱动的皱纹模式的物理机理。数值分析了无因次参数及其对控制皱纹方式的影响。对膜上皱纹特征的探索表明，可以通过设计晶格衬底来控制皱纹图案。我们的工作可以帮助理解复杂基材弯曲引起的皱纹，并指导新材料和新结构设计中皱纹的治理。对膜上皱纹特征的探索表明，可以通过设计晶格衬底来控制皱纹图案。我们的工作可以帮助理解复杂基材弯曲引起的皱纹，并指导新材料和新结构设计中皱纹的治理。对膜上皱纹特征的探索表明，可以通过设计晶格衬底来控制皱纹图案。我们的工作可以帮助理解复杂基材弯曲引起的皱纹，并指导新材料和新结构设计中皱纹的治理。
