Abstract

In this paper, the secondary buckling phenomena of the elastic rectangular plate subject to pure bending moments are investigated. The bifurcation points are classified numerically based on the determinant of tangential stiffness matrix and of its diagonal blocks obtained by means of the group-theoretic bifurcation theory. With reference to these blocks within the whole block-diagonalized one, the informations of the instability points and equilibrium paths after bifurcation are easily obtained. The quantitative influence of the initial imperfections are investigated based on the asymptotic laws and Monte Carlo simulations.
