摘要：Based on the natural exponential pair potential U(R)=Ce-R/λ0, the interaction potential between curved surface body and on surface particle is studied. Firstly, the interaction potential is written as a function of curvatures through the differential geometry. Secondly, idealized numerical experiments are designed to test the accuracy of curvature-based potential. Then, the driving forces induced by curvatures are analyzed, which confirms that micro/nano-curved surface bodies can induce driving forces; curvatures and the gradient of curvatures are the essential elements forming the driving forces. Finally, by combining with the curvature-based potential and driving forces, the movements on surface particles and the evolution of surface morphology of curved surface bodies are predicted. © 2019, The Chinese Society of Theoretical and Applied Mechanics; Institute of Mechanics, Chinese Academy of Sciences and Springer-Verlag GmbH Germany, part of Springer Nature.
