通过求解自洽弹性方程获得与 Lennard-Jones 势相互作用的软弹性颗粒的变形和粘附。在加载和卸载之间表现出滞后现象。此外，随着最大施加载荷的增加，拉脱力或最大粘附力也会增加并最终达到饱和。这两种现象的根源已通过实验观察到，可追溯到形状的有限平衡和动态滞后以及前进和后退变形固体之间的收缩角。
The deformation and adhesion of soft elastic particles interacting with a Lennard-Jones potential is obtained by solving self-consistently the elasticity equations. Hysteresis is demonstrated between loading and unloading. Also, the pull-off force or maximum adhesion is shown to increase and eventually to saturate as the maximum applied load is increased. The origin of both of these phenomena, which have been observed experimentally, is traced to limited equilibration and dynamic hysteresis of the shape and contract angle between the advancing and receding deformed solids.
