Shakedown Analysis by Elastic Simulation
2000Shakedown analysis of elastic plastic structures is widely credited as a valuable analytical/numerical tool for design purposes. For complex structures and loading conditions, e. g. for fast breeder nuclear reactor plants, full inelastic analysis is rarely performed, practically never within the early stages of the design advancement and the inherent ...

Shakedown Analysis of Elastoplastic Arches
Journal of Structural Mechanics, 1977Abstract The use of mathematical programming methods proves to be of interest in the formulation and the solution of some rather tedious problems of structural plasticity. This paper extends the application of linear programming techniques to elastoplastic arches under variable repeated loadings by adopting linearized models for the arch shape and the ...

LIMIT AND SHAKEDOWN ANALYSIS UNDER UNCERTAINTY
International Journal of Computational Methods, 2014Structural reliability analysis is based on the concept of a limit state function separating failure from safe states of a structure. Upper and lower bound theorems of limit and shakedown analysis are used for a direct definition of the limit state function for failure by plastic collapse or by inadaptation.

DYNAMIC ANALYSIS OF ELASTOPLASTIC SHAKEDOWN OF STRUCTURES
International Journal of Structural Stability and Dynamics, 2005This paper deals with the dynamics of a single-degree-of-freedom elastoplastic oscillator. The model adopted herein is useful for understanding the dynamic behavior of civil engineering structures, such as steel structures, especially when plastic inelasticity is of concern.

Shakedown Analysis of Curved Beams*
Journal of Structural Mechanics, 1984ABSTRACT Shakedown analysis of fixed-ended elastoplastic curved beams is presented. Both nonlinear and piecewise linearized yield conditions are considered. It is shown that the former assumption requires the solution of a nonlinear programming problem, while the latter assumption leads to a linear programming problem. Although these formulations cover

A Non-Cyclic Method for Plastic Shakedown Analysis
Computer Technology and Applications, 2003Shakedown is a cyclic phenomenon, and for its analysis it seems natural to employ a cyclic analysis method. Two problems are associated when this direct approach is used in finite element analysis. Firstly, the analysis typically needs to be stabilized over several cycles, and the analysis of each individual cycle may need a considerable amount of ...

Shakedown Analysis of Hollow Spheres
Journal of Engineering Mechanics, 1994This paper presents a detailed investigation of the shakedown behavior of thickâwalled hollow spheres subjected to cyclic temperature and sustained internal and external pressures. It is found that under sustained and cyclic loadings, the steady states can always be attained for kinematic hardening materials, and the shakedown mode is usually ...
