Abstract—The present work deals with the analysis of FRP composite cylinders. Two types of laminates, (1) cross-ply, and (2) angle-ply laminates are considered for the present analysis. Radial deflection and stresses are obtained by varying the diameter to thickness ratio (S), fiber orientation () in both the laminates. The problem is modeled with layered element of ANSYS software which is designed based on 3D-elasticity theory which can be successfully applicable for the analysis of thick FRP composite cylinders. Major findings: The composite cylinder with cross-ply obeying plane strain condition, so limited length model is sufficient for infinitely long cylinder analysis. The composite cylinder with angle-ply obeying plane strain condition with d/t ratio 100 and length is 15 mm, so the limited length model is sufficient to analyze the cylinder. For all other cases we need to analyze full length model.
