ABSTRACT
In this study strains, curvatures, and force and moment resultants for composite cylinders were determined using a FORTRAN code and graphical output. Results for the circular cylinder provided a baseline for the elliptical cylinder results, allowing a c mparison of the responses for different orthotropies (axially-stiff, hoop-stiff, and quasi-isotropic) and loadings (internal pressure and axial compression). This report shows a few of the responses and describes how the orthotropy and geometry affects he response of the cylinders under a load.
