摘要： 本文在二维近似下研究通过van der Waals力粘附于刚性衬底上的弹性薄膜脱粘问题。假设薄膜半无限长，并且受到边界处横向拉力。采用修正迭代法，本文导出了引发边界脱粘形核的临界拉力解析表达式。

Abstract： Detachment of a thin elastic film adhered onto a rigid substrate via van der Waals force is studied in the two-dimensional setting. The film is assumed semi-infite ling and undergoes a peeling force transverse to its edge. By using the modified iteration method, the critical peeling force which gives rise to detachment nucleation from the edge of the film is derived in an analytical form.
