Uncertainty Multimode Failure and Shakedown Analysis of Shells
2015This paper presents a numerical procedure for reliability analysis of thin plates and shells with respect to plastic collapse or to inadaptation. The procedure involves a deterministic shakedown analysis for each probabilistic iteration, which is based on the upper bound approach and the use of the exact Ilyushin yield surface.

On a numerical approach to shakedown analysis of structures
Computer Methods in Applied Mechanics and Engineering, 1980Abstract Two alternative ways of performing the shakedown analysis of structures subjected to variable repeated loads are presented. The first one enables one to check whether the structure shakes down (i.e. responds elastically after a few elastoplastic cycles) or not.

Limit and Shakedown Analysis of Periodic Heterogeneous Media
2001The paper deals with heterogeneous media with periodic arrangement of the inclusions (fiber-reinforced composites, perforated plates) and ductile components, subjected to either monotonic or variable repeated loading. The fundamentals of the theoretical static and kinematic approaches to the determination of the macroscopic yield strength of the ...

Limit and shakedown analysis of composites
1998The objective of this paper is to present a computationally cost effective approach to limit and shakedown analysis of metal-matrix composite materials. The analyses presented are based on: the homogenization theory for periodic media, the kinematic limit and shakedown theorems and the finite element method in its displacement formulation.

Shakedown Analysis at Finite Elastoplastic Strains and Deformations
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000AbstractA finite element method for shakedown analysis of structures that undergo finite elastic ‐ plastic strains and rotations is proposed The idea is the simultaneous computation of all relevant load cases coupled by a common plastic strain field.

Shakedown analysis of elastic-plastic structures
Nuclear Engineering and Design, 1974Abstract Behavior of elastic-plastic structures under repetitive and fluctuating loads is considered in this paper. Plastic deformation either stabilizes after a finite number of cycles or continues during the cycling. In the first case the structure is said to have shaken down to the boundary at the loading program.

Limit and Shakedown Reliability Analysis
2002In this chapter problems of load modelling for cyclic and variable repeated loading are discussed. Then, the general problem of time-invariant shakedown and limit reliability analysis in the load space is formulated. Also, the time-variant limit reliability analysis approach is shown.
