Abstract

A technique developed for calculating the discontinuity flaw of an adhesive contact and the adhesion energy for two bodies makes it possible to take into account these effects in designing a multilayer cermet wall (insulating barrier) of the liquid-metal blanket in a fusion-type reactor. The technique is based on a model of a linearly elastic medium, in which strains are proportional to external forces, and on the assumption that any body in equilibrium possesses minimum internal potential energy. Expressions are derived for calculating the area of an adhesive contact between two bodies and their adhesion energy. Calculation data illustrate the dependence of these two parameters on the values of the Young modulus and Poisson’s ratio for various pairs of materials, including the most suitable materials for insulating barriers of liquid-metal blankets.
