Elastic shear buckling capacity of the longitudinally stiffened flat panels

摘要

Various feasible approaches to the increase of the flat plate elastic shear buckling capacity are investigated. Based on derived theoretical envelopes of the considered approaches, stiffening parallel to the longer plate edges is identified as the most effective approach to the considered problem. An accompanying analytical formulation is approximated in a form convenient for utilization in structural analysis and design of the plated structures. All derived conclusions and proposed formulations are based on results of the numerous rationally designed numerical simulations utilizing the finite element method.
