Abstract

The buckling of a thin film deposited on an infinitely rigid substrate and delaminated over a finite length is studied in the framework of the Föppl-von Kàrmàn theory of thin plates. Assuming the two edges of the ductile film can fold, an energy-based analysis of the different morphologies of the film has been carried out. Depending on the delamination length, the film can either be unfolded, partially folded at one edge or symmetrically folded at its two edges.

刚性基底上韧性薄膜的屈曲和折叠

本研究在薄板的 Föppl-von Kàrmàn 理论框架下，研究了沉积在无限刚性基底上的薄膜在有限长度上分层的屈曲问题。假设韧性薄膜的两个边缘可以折叠，我们对薄膜的不同形态进行了基于能量的分析。根据分层长度的不同，薄膜既可以展开，也可以在一个边缘部分折叠或在两个边缘对称折叠。

期刊介绍： Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide: • a fast means of communication • an exchange of ideas among workers in mechanics • an effective method of bringing new results quickly to the public • an informal vehicle for the discussion • of ideas that may still be in the formative stages The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
