Rational magnification of the plate elastic shear buckling strength

Various feasible approaches to magnification of the plate elastic shear buckling strength are comprehensively 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, convenient for utilization in structural analysis and design of the plated structures, is approximated. Various recommendations and formulations relevant for determination of the rational stiffened plate design (with respect to the considered problem) are proposed. All derived conclusions and proposed formulations are based on results of the numerous rationally designed numerical simulations.
