In the work, an energy condition for the development of an isolated defect is obtained in the spatial case when destructive loads act both on the outer surface of the body and on the surface of the defect. Unlike the classical Griffiths fracture condition, the proposed condition clearly depends on the linear coefficient of thermal expansion and the temperature of the material. The model problem of the development of an isolated spherical defect is considered in the case when uniform pressures act on the boundary of the defect and on the remote boundary of the body.
