We consider a temperature changes near end of curvilinear crack with end zones of mate- rial cohesive forces in bending strip (beam). The aim of the local temperature changes is a delay or inhibition of crack growth. Boundary value problem for equilibrium of curvilinear crack under the action of external bending loads, induced thermoelastic stress field and trac- tions in bonds, preventing its disclosure, is reduced to a system of nonlinear singular integro- differential equations with the kernel of Cauchy type. Condition of crack limit equilibrium is formulated on the basis of a two-parameter fracture criterion.
