“…Effects of crack geometry and parameter of nonhomogeneity of material on the stress intensity, energy release and energy density were considered. In the work of Pavazza (2000), approximate analytical formulas for stresses and displacements in thin rectangular orthotropic or isotropic strips subjected to tension are presented. Shi (2015) devoted his investigation to analytical and numerical analyses of the doubly periodic arrays of cracks and proposes a precise solution procedure for describing the interaction effect in the doubly periodic rectangular-shaped arrays of cracks.…”

In the article, the pure bending problem for strip (beam) with straight, perpendicular to its axis crack located in the zone of tensile stresses is investigated on the assumption of narrow plastic strips near crack tips. Using methods of the theory of functions of a complex variable and complex potentials, the problem is reduced to the several linear conjunction problems. The solutions of latter problems are obtained in the class of functions confined in the edges of plastic strips. Formulas for the calculation of their lengths are derived. Expressions for the determination of crack tip opening values are written. Numerical analysis of the problem is performed.
