Elastoplastic Limit State of Inhomogeneous Shells of Revolution with Internal Cracks

By using an analog of the δc -model, we reduce problem stressed state and limit equilibrium inhomogeneous shell revolution weakened by internal crack any configuration with plastic strains developed on continuation in form a narrow strip to elastic problem. The indicated is then reduced system singular integral equations unknown limits integration discontinuous functions right-hand sides. We propose algorithm for numerical solution these systems regard conditions plasticity thin shells boundedness stresses. effects loading, geometric parameters, mechanical characteristics crack-opening displacement sizes zones are investigated cylindrical spherical made functionally graded materials containing parabolic cracks.
