Numerical Evaluation of Stress-Strain State of Bending Plates Based on Various Models

Abstract In practice, the most common analysis methods of bending plates are the Kirchhoff model and the first-order shear model. In this paper analysis results of a freely supported bending plate of various thickness are given according to the Kirchhoff model, the first-order shear model and the 3d elastic model. For solving of this problem numerical algorithms of the finite-difference energy method and the finite element method are used. The solving of contact problem and the comparative appraisal of obtained results are also given.
