A Plane-Strain Elastic Stress Solution for a Multiorthotropic-Layered Cylinder

Abstract

In 1963 Lekhnitskii published the equations that describe the distribution of stresses in a monolayered anisotropic cylinder under the influence of various loading conditions. Recently, O'Hara simplified these equations for the case of an orthotropic cylinder and cast them into a form that is convenient to use. This report discusses the methodology of constructing the stress solution for a multiorthotropic-layered cylinder under plane-strain boundary conditions, i.e., all orthotropic layers have zero axial strain. Combined loadings of internal and external pressure are allowed. Solutions for a selected layup and loading conditions are compared with finite element results and show excellent agreement. In addition, a procedure to obtain the stress solution when an interference exists at the interface of two orthotropic layers is discussed. Keywords: Stress distribution, Orthotropic, Multilayered, Cylinder, Composite.
