Strength criteria for thin orthotropic shells. Part 2: Calculation and analysis
Various strength criteria for orthotropic materials have been analyzed. The results of calculating the strength of a cylindrical shell made of fiberglass for various strength criteria (criteria of maximum stresses, Mises-Hill, Fisher, Goldenblat-Kopnov, Pisarenko-Lebedev) are shown. The development of zones failing to meet the strength requirements with increasing load is analyzed. The calculation is carried out in accordance with the geometrically nonlinear mathematical model of deformation of the shell taking into account the transverse shears and material orthotropy.
