Abstract

This study is concerned with the structural analysis and optimal design of sandwich composite cylinders having ortho-grid core and frp skin. The related stability problems are numerically solved using a degenerated shell finite element model. First, equivalent extensional, bending, and shear stiffnesses for the proposed configuration are obtained. Then, optimal designs are obtained for some selected geometries and material properties using a simple graphical optimization method.
