ANALISIS OF THE “BOUNDARY LAYER“ STRESS-STRAIN STATE IN FRAMES OF THE NONCLASSICAL CYLINDRICAL SHELL THEORY

Two variants of a refined theory of determining the stress-strain state in the boundary zone of a cylindrical shells are represented. As an example the calculations of a shell with rigidly restrained on two edges and under the influence of local distributed and concentrated loadings is considered. The Comparison of calculation results of the stress-strain state shell obtained in this work and by the classical theory is given

closed cylindrical shell, two variants of refined theory, approximation by polinomials, virtual principle of Lagrange, edge conditions, Laplace transform, local loading, the characteristic equation, “boundary layer”, normal transverse stress
