A typical cross section of the strengthened I ... WebMar 1, 2024 · Specifically, buckling in beams arises when, due to the annihilation of the effective stiffness caused by compressive loads beyond a critical value, considerable out-of-plane bending displacements appear. The literature on buckling and postbuckling of beams is wide and, at the same time, also scattered.
WebDisplacement solutions, von Mises stress solutions and buckling modes are discussed in detail. The prediction accuracy and meshes are compared with the shell-type model and beam-shell-type model in ABAQUS software, which indicates the high applicability and efficiency of the proposed analysis method for various types of stiffened panels.
