毛细管力作用下的软衬底变形预测在冶金、材料科学、航天、微纳米技术等领域得到了广泛的关注，也是对经典杨氏公式的补充。利用能量原理和连续介质力学方法，对弹性衬底在毛细管力作用下的变形进行了定量分析。研究了实际液滴的形态，并与经典的液滴球形假设计算的液滴形态进行了比较。得到了基片的位移场，并讨论了其在液滴边缘的奇异性。研究结果对工程应用和微纳米测量具有一定的指导意义。(C)2008年，爱思唯尔出版。
Prediction on the deformation of a soft substrate induced by capillary force has been widely paid attention in the broad range of applications, such as metallurgy, material science, astronavigation, micro/nano-technology, etc., which is also a supplementary result to the classical Young's equation. We quantitatively analyzed the deformation of an elastic substrate under capillary force by means of the energy principle and the continuum mechanics method. The actual drop's morphology was investigated and was compared with that calculated based on the classical spherical shape assumption of the droplet. The displacement field of the substrate was obtained, especially, its singularity at the droplet edge was also discussed. The results are beneficial to engineering application and micro/nanomeasurement. (C) 2008 Published by Elsevier B.V.
