Influence of a Flexible Coating on the Strength of a Shallow Cylindrical Shell with Longitudinal Crack

Resumo

We study the problem of tension of a cylindrical shell containing a longitudinal crack and strengthened by a coating. The flexible coating is modeled by a hinge connecting the faces of a notch on one face of the shell. We determine the stressed state near the crack tips and analyze the distribution of the hinge reaction in the coating. The limit equilibrium of the shell weakened by a crack is analyzed with regard for the limited strength of the reinforcement.
