Local buckling and deformation capacity of tubes in steel structures
(2008)In this paper, the focus is on local buckling limits after yielding of the cross section (plastic buckling). This is in contrast to thin cylindrical shells, where local buckling occurs at stresses below the yield stress ... -
Local buckling strength and deformation capacity of pipes
(2009)Local buckling in cylindrical shells may occur elastically or plastically, mainly depending on the diameter to wall thickness ratio. In offshore structures plastic local buckling is mostly the governing criterion. In thin ... -
