摘要：

Abstract: The research results are obtained on the basis of a technique implementing the finite element method for solving problems of strength and stability of discrete-reinforced cylindrical shells made of the composite material, taking into account the momentness and nonlinearity of their subcritical stress-strain state. The stability of an anisogrid circular cylindrical shell made of a composite material under pure bending with internal pressure is investigated. We determine the effect of deformation nonlinearity, reinforcing set stiffness, reinforcement layup angles, shell thickness, and internal pressure on the critical loads of the shell instability. © Allerton Press, Inc. 2024.
