Nonlinear Buckling and Post-buckling Analysis of laminated Composite Cylindrical Shells Subjected to Axial and Pressure Loads

摘要：

　　Thin walled cylindrical shells and panels are more susceptible to failure in buckling rather than material failure.In present study,non-linear buckling analysis of GFRP cylindrical shells under axial compression combined axial load and internal pressure is carried out by using general purpose finite element program (ANSYS).Nonlinear buckling analysis involves the determination of the equilibrium path (or load deflection curve) up to the limit point load by using the Newton-Raphson approach.Limit point loads evaluated for various geometric imperfection magnitudes shows an excellent agreement with available experimental results.The influence of R/t ratio on mode transition behavior is briefly highlighted.
