Abstract

An experimental investigation was carried out to determine the strain distribution around circular holes in crossply and angleply laminated E Glass-Epoxy composite cylindrical shells subjected to axial tension. The surface strains in the shells were measured using strain gauges. The strains were also obtained by finite element analysis using a high precision triangular cylindrical shell finite element. In the linear range of stress-strain response for these composites, fair agreement was found between the experimental results and finite element predictions.13;
