Abstract
The stability of anisotropic cylindrical shells under torsion in spatial position
Highlights
Composite cylindrical shells are widely used in various designs of modern technology
Experimental testing and implementation of the capabilities of the proposed approach determine the consideration of the circular cylindrical shell stability to torque
Where τ cr zθ is the critical value of the shell shear stress, and the divergence of the reinforcement directions and the axis of the shell is determined by the angle ψ
Summary
Composite cylindrical shells are widely used in various designs of modern technology. Sometimes their operating conditions are such that shear stress occurs in the shells and can reach critical values. The magnitudes of these stresses could are known from previously performed tests or found by calculation. Methods for calculating composite shells in spatial formulation using mathematical models of varying degrees of accuracy have been developed (Novozhilov, 1948; Lekhnitskiy, 1977; Guz’ & Babich, 1985; Grigorenko, Vasilenko & Pankratova, 1991; Kardomateas, 1995; Kardomateas & Philobos, 1995; Bazhenov, Semenyuk & Trach, 2010). There is a need to develop methods aimed at solving the problems of composite shell stability using a more general model of a composite with low material symmetry
