液滴作用下弹性梁的弯曲:变分法

The bending of an elastic beam by a liquid drop: A variational approach

Sebastien Neukirch, Arnaud Antkowiak, Jean-Jacques Marigo

摘要:

本文研究了在弯曲效应占主导地位的情况下液滴与弹性梁的相互作用。我们使用变分方法推导出系统的平衡方程中存在的重力和存在或不存在的接触线钉扎。我们表明,推导出的平衡方程的梁子系统揭示了外力施加在梁上的液相和汽相。其中,在三线(三相相交的曲线)处施加的力被发现沿着液-气界面。

英文摘要:

We study the interaction of a liquid drop with an elastic beam in the case where bending effects dominate. We use a variational approach to derive equilibrium equations for the system in the presence of gravity and in the presence or absence of contact line pinning. We show that the derived equilibrium equations for the beam subsystem reveal the external forces applied on the beam by the liquid and vapor phases. Among these, the force applied at the triple line (the curve where the three phases meet) is found to lie along the liquid-vapor interface.
