Application of shakedown theory in track substructure design
Proceedings of the Institution of Civil Engineers - Ground Improvement, 2019Tracks require high performance of earth structures against excessive residual settlement under repeated train loads. In the current design standards, the quality of soil materials and compaction control are strictly prescribed based on empirical knowledge and scale tests; however, construction costs become relatively high accordingly. A more rational

Advanced Material Modelling in Shakedown Theory
2002The aim of this lecture is to present possibilities how to extend the validity of shakedown theory to other than linear elastic-ideal plastic or linear elastic- unlimited linear hardening material behaviour in conjunction with the validity of the normality rule.

Analysis of pressure equipment by application of the primal‐dual theory of shakedown
Communications in Numerical Methods in Engineering, 2006AbstractThe paper describes the application of the primal‐dual theory of limit and shakedown analysis in safety assessment and design of pressure components according to the new European approach to design by analysis. Two methods, the static and kinematic one, and their combination, the primal‐dual method, are discussed.

Application of Shakedown Theory and Numerical Methods
2002In this lecture, the methodological framework for the numerical application of shakedown analysis is developed. Examples of applications such as the analysis and optimisation of composite materials and the analysis of various plates and shells problems are presented.

An extended shakedown theory on an elastic–plastic spherical shell
Engineering Structures, 2015Abstract The article analyses one of possible optimization methodologies for ideal elastic–plastic structures at shakedown and its application for shallow spherical shells having prescribed geometry and affected by a variable repeated load (VRL) – a system of external forces that may vary independently of each other.

The Reliability of Bar Structures in the Light of the Shakedown Theory
1992A series of works dealing with the evaluation of the reliability of structures where the possibility of plastic strains is taken into accound have been published in recent years. In most of them, however, the problem is considered from the point of view limite state capacity [1–4].

Geomechanical Analysis of Unbound Pavements Based on Shakedown Theory
Journal of Geotechnical and Geoenvironmental Engineering, 2000A procedure for analyzing the mechanical response of an unbound pavement to the repeated loading of traffic is presented. The pavement is modeled as a layered elastic/plastic structure, and its response is described by the concepts of shakedown theory. A critical shakedown load is identified as the key design parameter.

Implementation of shakedown and packing theories for unbound granular materials
2017Enhancing the load bearing quality of granular layers is fundamental to optimize the structural performance of the pavements. Unbound granular materials are one of the most used materials in the base layers of pavements. There have been growing interests on the behavior of unbound granular material in road base layers. Both design of a new pavement and
