A finite element program is developed to analyze a composite laminate structure axisymmetric geometry and loading. Circumferential displacement is considered in addition to the radial and axial. The fiber orientation may be oblique to the axis. Thus, each nodal point has three degrees of freedom and the procedure models the complete state of stress and strain. The program is verified by application to cross-ply and angle-ply coupons. A segment of a large radius axisymmetric ring under uniform radial pressure is equivalent to a free- edge delamination coupon. The stress field from the axisymmetric analysis is compared with the results of a higher order finite element analysis of a free- edge delamination coupon. Additionally, the computer program has the capability to solve a variety of problems including tubular angle-ply specimens, nozzles, etc. Composite Laminated, Finite Element Method, Delamination, Stress Analysis.
