    Some contributions into a solution for plastic mechanisms in thin-walled beams
    (Wydawnictwo Politechniki Łódzkiej, 1997) Kotełko, M.
    Two contributions into the problem of plastic mechanisms in thin-walled box-section beams are presented in the paper. The first solution concernes a beam built of strain-hardening izotropic material and incorporates membrane strain energy in the total energy of plastic deformation. The second solution takes into account orthotropic properties of a beam material while a rigid-perfectly plastic behaviour of the material is considered. Numerical results are presented in diagrams showing an energy of plastic deformation and bending moment at the global plastic hinge in terms of rotation angle at that hinge.
