Countable model of static effect of non-local interaction in elastic composite circular disc

The paper deals with the static analysis of circular disc in a rotationally-symmetric state of deformation. The effect of elastic non-local interaction between the material of disc and the thin layer of hardening agent on the edge is taken into consideration. A countable model of the problem is formulated and a solution method of the govering equation is proposed. Numerical results show that the synergetic effect is observed in the boundary zone of the disc.
