Combined Action of Bending and Tension of an Isotropic Plate with Through Crack in the Absence of Contact between the Faces and with Regard for the Plastic Zones and Hardening of Material at the Tips

We study the problem of combined bending and tension an isotropic plate containing a through crack by distributed moments forces at infinity in absence contact between faces external loads applied to but presence plastic zones its tips. also take into account phenomenon hardening material satisfying Tresca plasticity conditions form surface layer or hinge. By using complex potentials plane classical theory plates, we obtain analytic solution class functions bounded tips zones. present dependences for lengths opening displacements The numerical analysis these is performed different parameters problem.
