In the present research, the effects of fiber orientation in buckling load of composite cylinders shells in different lay-up sequences under axial and torsion loading have been investigated. A parametric study for different lay-up sequences is given with changing with 5 Degree step the fibre orientation from 0 to 90 degree. A numerical simulation using FE commercial program Abaqus was used to acquire critical buckle load according to Eigenvalue buckling prediction method. First the validity of the results is checked by making comparison with experiments references and very good agreement is achieved.
