An Indirect Incremental Method for Shakedown Analysis Based on the Min-Max Approach

  • Sławomir Pycko
Part of the Solid Mechanics and Its Applications book series (SMIA, volume 36)

Abstract

A numerical algorithm based on the Newton-Raphson iterative scheme is proposed for a determination of limit analysis and shakedown load multipliers. A fictitious tangent matrix for variable loading is indirectly derived from the min-max formulation of the shakedown problem. It reduces the complex analysis of structures under variable loading to a certain equivalent fictitious incremental problem. A fast convergence of the procedure is illustrated on examples of space frames.
