Influence of Transverse Shear and Transverse Normal Stress on Large Deflections of Orthotropic Arches

Abstract

The problem of finite-amplitude deflections of a thin, elastic, shallow arch subject to uniform normal pressure is investigated. A COMPOSITE- MATERIAL ARCH IS INVESTIGATED WHEREIN CLOSELY SPACED GLASS REINFORCING ELEMENTS IN THE FORM OF EXTREMELY SMALL DIAMETER RODS ARE ORIENTED NORMAL TO THE ARCH MIDDLE SURFACE AND BONDED INTO AN EPOXY MATRIX. Transverse shear and transverse normal stress effects are included, as well as initial geometric imperfections in the structure. The governing equations are derived and solved by several approximate techniques to yield load-deflection characteristics from which buckling loads are obtained. The analytical results are confirmed through a series of experiments conducted on such arches.
