Consider the plane-strain rigid-perfectly plastic deformation of a granular material which satisfies the stress equilibrium equations and the Coulomb yield criterion.
The numerical integration of the stress equilibrium equations, exploiting their hyperbolic character, governing the ideal plastic plane deformation of a granular material is considered.
In the first step, displacements are obtained using a post-processing procedure based on the three-dimensional stress equilibrium equations and the thermoelasticity equations, from the results of FSDT finite element analysis.
Based on the incremental complementary energy principle, a stress hybrid model is developed for the geometrically nonlinear analysis of beams. According to the requirement of the compatibility of both interior and boundary displacements for an element and the equilibrium of the stress field of the element, we derive the finite element formulas which include only the unknown nodal displacements. Then, a two bode shallow beam element with twelve degree of freedom is established. Since the ge...
