The Collapse of Composite Cylindrical Panels with Various Cutout Locations Considering Material Degradation.

Abstract

The purpose of this thesis is to study the effects of material degradation on panels with cutouts. To observe this effect, one first has to establish the critical positions of specific size cutouts within the panel. In order to do this, the effect of a cutout located at different positions within the composite cylindrical panel subjected to an axial loading will be studied analytically using the structural Analysis of General Shells (STAGSC-1) computer program. Then secondly, material degradation effects due to temperature and moisture at the critical cutout locations will be analyzed. Upon completion, this thesis will allow for a better understanding of axially loaded composite cylindrical shells with cutouts under less then perfect conditions. Keywords: Shell analysis, Finite elements.
