“…Various types of elasto-plastic behavior of a beam under steady axial force and cyclic bending moment will be discussed below. Using Bree's familiar notation (Bree, 1967(Bree, , 1989, the load regime diagram is divided into various regions, i.e. elastic (E), shakedown (S), plastic fatigue (P), ratcheting (R), and plastic collapse (C p ).…”

“…Therefore, the incremental Finite Element Analysis (FEA) is widely used. In fact, the step-by-step elastic-plastic FEA can only obtain whether the shakedown, reverse plasticity, or ratchetting occurs under the predefined cyclic loading, which requires many repetitive calculations to generate the Bree-like diagram [1].…”

Traditionally, the shakedown or ratchet analysis mainly focus on the structure under general cyclic loading condition composed by constant mechanical load and cyclic thermal load, but the investigated steam turbine rotor here is subjected to cyclic mechanical load and cyclic thermal load that vary in phase and out of phase throughout the practical operation load cycle.The failure behaviours of structure under practical operation load cycle is studied and discussed. The novel shakedown and ratchet failure diagrams are plotted by calculating different combinations of cyclic mechanical load and cyclic thermal load. The innovative equation to acquire plastic strain range of the structure under steady state cycle is fitted, which is vital for low cycle fatigue (LCT) assessment.Moreover, detailed step-by-step inelastic analyses are also performed to verify the applicability and effectiveness of the limit boundaries calculated by the LMM. All the investigations demonstrate that the proposed LMM technique is capable of handling practical industrial application with complicated cyclic loads.

“…The complexity of shakedown means that analytical solutions are rare, and thus incremental Finite Element Analysis (FEA) is widely used. Incremental FEA can only show if elastic shakedown, plastic shakedown or ratchetting occurs, and therefore many calculations are required to generate the Bree-like diagram [2].…”

This paper presents the shakedown analysis of welded pipes subjected to a constant internal pressure and a varying thermal load. The Linear Matching Method (LMM) is applied to investigate the upper and lower bound shakedown limits of the pipes. Individual effects of i) geometry of weld metal, ii) ratio of inner radius to wall thickness and iii) all material properties of Weld Metal (WM), Heat Affected Zone (HAZ) and Parent Material (PM) on shakedown limits are investigated. The ranges of these variables are chosen to cover the majority of common pipe configurations. Corresponding individual influence functions on the shakedown limits are generated. These are then combined to allow the creation of a safety shakedown envelope, which can be used for the design of any welded pipes within the specified ranges. The effect of temperature dependent yield stress (in PM, HAZ and WM) on these shakedown limits is also investigated
