文摘The wrinkling law of annular sheet which is induced by capillary force with inner liquid film is analyzed in this paper.The results show that the inner liquid film can wrinkle the annular sheet when the surface tension of the liquid film reaches a critical value,and the critical value can be dramatically altered by changing the geometry and properties of the annular sheet.The results obtained in this article may hold potential applications in generating three-dimensional structures through capillary effects.
