Abstract
The cylindrical shell of stepped lengthwise section made of a composite material with rigidly fixed and freely displaced in longitudinal direction end edges, under the action of the internal uniformly distributed load is examined. The problem of the stress-strain state of orthotropic cylindrical shell in plan is studied in a refined statement. With the assigned overall dimensions of the shell and its constant weight equal to the weight of the shell of a constant thickness, the optimum values of its geometric and physical parameters are determined, ensuring the greatest bearing capacity of the shell.
