Analysis modeling for plate buckling load of vibration test
      
The analytical buckling solutions should be very useful as benchmark values for testing the validity, convergence and accuracy of numerical techniques for plate buckling.
      
This study shows the importance of including the prebuckling deformation in thick plate buckling since its effect is in the same order of magnitude as that of shear.
      
In the present contribution, an attempt is made to formulate a bone-plate buckling theory using Cowin's concepts of adaptive elasticity (Cowin and Hegedus in J Elast 6:313-325 1976; Hegedus and Cowin J Elast 6:337-352 1976).
      
The development is outlined of the first author's Simplified Plate Buckling Criterion which is based on nonlinear theory.

In this paper,the curved shell finite element method is adopted to analyse the ultimate strength of stiffened plates under compression with different stress gradients as well as the interaction curves P'/P_y'-M'/M_p' of thin-walled box sections and the ultimate strength of axially and eccentrically loaded box columns in consideration of the post-buckling effect of plates.All initial im- perfections are taken into account in analysis.Comparison between the results of the prevailing specifications and the theory of this paper is presented. Errors of the specifications are checked,Equations for calculating the ultimate strength of axially loaded and pure bending stiffened plates and thin-walled box sections are proposed according to the theoretical results.A simple interaction equation is presented for calculating the ultimate strength of eccentrically loaded sections and finally effective design methods for axially and eccentrically loaded columns are suggested,The results of the suggested methods are in good agreement with that of the finite element method.

A semi-energy method to analyse the buckling behaviour of edge-stiffened plates under combined compression and bending is presented in this paper, One unloaded edge of the plate is restrained elastically against rotation and the other is stiffened by a stiffener or lip. The maximum stress is applied either to the rotationally restrained edge or to the lip. The deflec- tion form across the plate is assumed to be a transcendental function similar to the vibration function of the beam. A comparison between our theoretieal results and Timoshenko's conclusions is made and agreement is seen to be good. Some wrong results obtained by Timoshenko are also corrected in this paper.
