Although negligible at large scales, capillary forces may become dominant for submillimetric objects. Surface tension is usually associated with the spherical shape of small droplets and bubbles, wetting phenomena, imbibition, or the motion of insects at the surface of water. However, beyond liquid interfaces, capillary forces can also deform solid bodies in their bulk, as observed in recent experiments with very soft gels. Capillary interactions, which are responsible for the cohesion of sandcastles, can also bend slender structures and induce the bundling of arrays of fibers. Thin sheets can spontaneously wrap liquid droplets within the limit of the constraints dictated by differential geometry. This review aims to describe the different scaling parameters and characteristic lengths involved in elastocapillarity. We focus on three main configurations, each characterized by a specific dimension: three-dimensional (3D), deformations induced in bulk solids; 1D, bending and bundling of rod-like structures; ...

弹性毛细管作用：当表面张力使弹性固体变形时

尽管在大尺度上可以忽略不计，但毛细力可能会成为亚毫米物体的主导力量。表面张力通常与小液滴和气泡的球形形状、润湿现象、吸入或昆虫在水面的运动有关。然而，除了液体界面之外，毛细管力也可以使固体体积变形，正如最近用非常软的凝胶实验所观察到的那样。导致沙堡凝聚的毛细管相互作用也可以弯曲细长结构并导致纤维阵列的捆绑。薄片可以在微分几何所规定的限制范围内自发地包裹液滴。本综述旨在描述涉及弹性毛细血管的不同缩放参数和特征长度。我们专注于三个主要配置，每个配置都有一个特定的维度：三维 (3D)，在散装固体中引起的变形；1D、棒状结构的弯曲和捆扎；...
