Shakedown Analysis by Elastic Simulation

2000
Shakedown 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 ...

LIMIT AND SHAKEDOWN ANALYSIS UNDER UNCERTAINTY

International Journal of Computational Methods, 2014
Structural 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, 2005
This 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, 1984
ABSTRACT 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, 2003
Shakedown 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, 1994
This paper presents a detailed investigation of the shakedown behavior of thick‐walled 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 ...

Shakedown Analysis of Nonsandwich Structures*

Journal of Structural Mechanics, 1984
ABSTRACT This paper presents a simple method of evaluating the alternating plasticity limit of structures with nonsandwich cross sections under combined stresses. Mathematical programming and matrix formulations are used. A procedure that enables the actual shakedown limit of the nonsandwich structure to be found is then given.
