The effective elastic modulus and fracture toughness of the nanofilm were derived with the surface relaxation and the surface energy taken into consideration by means of the interatomic potential of an ideal crystal. The size effects of the effective elastic modulus and fracture toughness were discussed when the thickness of the nanofilm was reduced. And the dependence of the size effects on the surface relaxation and surface energy was also analyzed.

Forming Process

Size effects are effects which might occur, if the dimensions of a forming process are scaled up or down. They might enable or disable the application of a process in the micro range. Based on the systematic order of size effects, which defines density, shape and structure effects, one example for each group is given. A density effect, which occurs in Tiffany structures, explains the changes in forming behavior of foils with respect to the forming limit diagram. The feasibility of a new heading process only in the micro range is due to a shape effect, driven by the surface energy. The changes in the tribology in deep drawing by a structure effect, known as closed an open lubricant pocket model, can be explained only if one takes the temperature dependence of the viscosity of the lubricant into account.

The paper proposes an empirical model, which in combination with the model of A.I. Rusanov. makes it possible to calculate the anisotropy of the surface energy and the thickness of the surface layer of metals and their compounds. Calculations were made for six metal chalcogenides. The surface energy and the thickness of the surface layer have a significant effect on nanoelectronics, since in the nanoregion, size effects affect all physical effects

The surface effect can be significant for nanoscale structures, and the surface energy is expected to be prominent in governing the geometric size-dependent deformation and strength mechanisms of single crystals at the nanoscale. In a new numerical method which combines surface energy and three-dimensional finite element analysis, size effects on the stiffness matrix with surface effects was studied numerically. Results show the surface stiffness matrix is more and more important relative to the bulk stiffness matrix with the size of elements decreasing.
