The authors discuss a problem about the stress state of an elasto-plastic isotropic shell of arbitrary curvature with an internal crack, with allowance for material hardening. A system of singular integral equations is obtained and solved numerically by the mechanical quadratures method. The effect of material hardening on basic characteristics of the stress state is studied.
