CHARACTERIZATION OF THE PHYSICAL PROPERTIES OF WEB-STIFFENED SANDWICH STRUCTURES.

Abstract

Presented is a means of representing the physical properties of and stress-strain laws for circular, cylindrical, web-stiffened sandwich shells. The face layers are treated as thin shells in which the classical theory of shells applies, while shear deformations are permitted in the core. Except for the inclusion of an average second-order shear modulus, the structural core is treated as a layer of inhomogeneous, orthotropic material comprised of a series of webs considered as discrete elements. A partial justification of the concept of an average secondary shear modulus is given by the results of two static beam-type problems involving web-stiffened structures. (Author)
