Abstract

Laminated, alternate-ply cylindrical shells of finite length are analyzed using the Donnell equations and classical laminated shell theory. Separate solutions are obtained for shells with an even and an odd number of layers as necessitated by the two different types of mechanical coupling involved. Integration constants are evaluated for free end conditions. Numerical results presented are focused on lamina stresses in the principal material directions resulting from the separate influences of uniform internal pressure, a uni form temperature change and a linear temperature change profile that is skew-symmetric with respect to the middle surface of the shell, and their sensitivity to the total number of layers in the shell. Simplified, algebraic expressions for the thermal stress resultants are derived for the two tempera ture change profiles.
