摘要

It is proposed to simulate the action of surface tension forces by creating a thin elastic layer on the surface of the material. It is shown that the layer should be considered as an incompressible medium. The changes in the volume of the elastic material are possible only artificially by changing the value of a special parameter that allows one to get the desired effect of the material surface. It is shown that the mechanical properties of the elastic layer should be determined by the refined Neo-Hookean potential. It has been established how the parameters of the potential and the layer thickness are related to the value of the surface tension coefficient. An example of computational modeling the influence of the surface effects on changes in the relief of an elastomeric sample is given. Solid particles of spherical shape covered by a thin layer of a binder are located near the sample boundary. It has been established that the curvature of the material surface leads to the deformation of the elastomeric matrix at the nanoscale level of the material near its boundary with the environment. This deformation is the result of the action of the surface tension forces. This phenomenon should be taken into account during the atomic force microscopy analysis of the structure and properties of elastomeric nanocomposites.
