Stability of Cylindrical Shells with Microdamages

Problems on bifurcational stability of cylindrical shells are formulated and solved within the framework of the Kirchhoff–Love hypotheses with regard for damageability in the precritical stress state. The damageability of the material is due to the inhomogeneity of its microstrength and is modeled by empty quasispherical pores whose distribution over the shell volume is statistically homogeneous and isotropic. The problems are solved for shells under axial and radial compression.
