报告摘要：

Elastocapillary phenomena involving elastic deformation of solid structures coupled with capillary effects of liquid droplets/films can be observed in a diversity of fields, e.g., biology and microelectromechanical systems (MEMS). In this talk, we will demonstrate what we have done in recent years. The topic mainly deals with the following aspects:

(1) Capillary adhesion of micro/nanobeams (nanowires, nanotubes, and MEMS structures). We proposed a new approach, i.e. the energy functional variation with movable boundary conditions to solve this kind of problem.

(2) Abnormal bending of microbeams or microplates. We presented the analytical solutions of the beam/plate deflections induced by capillary forces, and the results are compared with FEM simulations.

(3) Capillarity induced microtube deformation. We calculated the deformation caused by a droplet inside or outside of a microtube, based on the Mooney-Rivlin constitutive relation.

These analyses can also be generalized to investigate the buoyant force of a water strider, and the adhesion of a cell on a solid substrate.
