The effect of nonlinear properties, shear stiffness, geometric and physical-mechanical parameters of the composite material on the stress-strain state of spherical, conical and cylindrical members of rockets with holes was numerically investigated. A number of both evident and new mechanical effects regarding the orientation of the axes of orthotropy in the shell and the mutual influence of nonlinearity and transverse shear on the stress state of rocketry members have been detected.
