Post-buckling behaviour of slender structures with a bi-linear bending moment-curvature relationship [PDF]

, 2007
Certain classes of slender structures of complex cross-section or fabricated from specialised materials can exhibit a bi-linear bending moment–curvature relationship that has a strong influence on their global structural behaviour.

Buckling of multi-layer semi-auxetic meta-plates

Composites Part C: Open Access
Cellular meta-plates combine the advantages of mechanical metamaterials and cellular materials, but their application is often limited by low post-buckling stiffness and premature failure under compression. Here, we studied the buckling and post-buckling

A new approach to the stability problem of plates subjected to arbitrary complex loading

Vietnam Journal of Mechanics, 1992
The pre-buckling and post-buckling deformation processes are assumed to be less complicated, i.e. processes of average curvature, the influence of complex loading on the stability of plates was analyzed in [1]. In this paper eliminating this restriction,
