non-uniformly heated annular disk, cracks with interfacial bonds, pre-fracture zone, cohesive forces.

The limit-equilibrium state of non-uniformly heated annular disk, weakened by a system of rectilinear cracks with end pre-fracture zones is investigated. Using deformation fracture criterion the relation allowing to determine the critical value of the intensity of the heat effect on the disc at which the cracks growth is obtained.
