Abstract

Abstract

A method of determining bifurcation directions at a double eigenvalue is presented by combining the finite element method with the perturbation method. By using the present method, the buckled states of rectangular plates at a double eigenvalue are numerically analyzed. The results show that this method is effective.
- double eigenvalue,
- bifurcation directions,
- FEM,
- perturbation method,
- buckling of rectangular plates
