The configuration of film-substrate structure is widely involved in many aspects of technologies. To ensure high reliability and sound performance, it is of importance to understand the stress distribution and the adhesion at the interface. In the present work, within mind the film of finite width, a mechanical model has been proposed to analyze the traction at the interface between the film and an elastic substrate that may be subjected to either uniaxial stretching or bending. For incompressible substrates, the problem may be reduced to the solution of singular integral equations of Cauchy type and the tractions at the film’s edges have been revealed to exhibit the square-root singularity. Mode mixity has been calculated. By comparing the strain in the film when the system is subjected to uniaxial stretching with that from experiments on the adhesion between graphene and substrates, an agreement has been found and the implications of the present model in the measurement of adhesion energy have been discussed.

关于粘合到弹性基材上的有限长度薄膜的应力传递和模态混合

薄膜基板结构的配置广泛涉及技术的许多方面。为了确保高可靠性和良好的性能,了解界面处的应力分布和附着力非常重要。在目前的工作中,考虑到有限宽度的薄膜,已经提出了一个力学模型来分析薄膜和弹性基材之间的界面处的牵引力,该弹性基材可能会受到单轴拉伸或弯曲。对于不可压缩的基材,问题可能会简化为柯西型奇异积分方程的解,并且薄膜边缘的牵引力已显示出平方根奇异性。已计算模式混合。
