Elastoplastic Analysis of Structure Composed of Columns Based on the Basic Equation System

Abstract:

Textbooks of plasticity mechanics have given example for elastoplastic analysis of structure composed of columns, but the given example is solved with the method of material mechanics. There is actually some difficulty to solve the structure composed of columns with the basic equation system of the classical plasticity mechanics. The new equation system of plasticity mechanics based on e-p curve has advantage over the classical one. In this paper, the solution will be really obtained with the basic equation system of plasticity mechanics based on e-p curve, which is not only a job to solve a simple problem with the basic equation system, but also a demonstration to show that the new equation system of plasticity mechanic based on e-p curve is correct and practicable.
