000012695 520__ $$2eng$$aAnisotropic elastic/plastic buckling of plates is approached as a bifurcation problem. The pre-buckling loading stresses σ νν = ασ ξξ ,−1 ≤ α ≤ 1, are aligned with ξν support axes of a simply supported rectangular plate. The ξν axes are at an angle β with respect to the xy principal axes of anisotropy. Analytical variational method is employed with the usual assumptions, and Hill’s theory of anisotropic strain-hardening plasticity. Bifurcation stresses are found for the anisotropic, and the classical isotropic incremental and deformation theories of plasticity, for equibiaxial compression (α = 1), equal compression and tension (α = −1), and the uniaxial (α = 0 ) cases. Plastic buckling paradox is examined for all three cases.
