Abstract
It is well-known that, nano-mechanics should take into account not only physical phenomena occuring within the bulk but, first of all, the physical phenomena appropriate for a surface of two materials contact. The huge volume density of internal surfaces as well countours lines located within the nanomaterial results in our interest in, apart from classical form of mass, momentum and entropy transport, those modes of transportation where a carrier of physical property follows a free path having of a dimension greater than nanostructure characteristic dimension. The mode of transport dominated by mechanical, thermal and electrical slip of carried bounding off walls (a surface of separation) is called usually in physics ”a ballistic mode”. In the paper the appropriate Newtonian surface vis impressa responsible for the ballistic mode of transport is defined, classified and explained. We postulate that generally surface vis impressa can be additivelly splited onto friction and mobility forces.
