The lowest approximate bifurcation load of a real structure with initial imperfection is determined. The investigation is performed for a Z-column made of carbon-epoxy laminate. The amplitude of initial imperfection is small. The column is simply supported on both ends. All calculations are performed by the finite element method and Koiter’s method. First, an eigenvalue buckling problem is solved to determine bifurcation loads. Next, post-buckling equilibrium paths for the plate structures are determined to calculate the lowest approximate bifurcation loads by the P-w and P-w2 methods, the inflection point method and the Koiter’s method. |
