Plastic Shakedown Behavior and Deformation Mechanisms of Ti17 Alloy under Long Term Creep–Fatigue Loading

open access: yesMetals
Ti17 alloy is mainly used to manufacture aero-engine discs due to its excellent properties such as high strength, toughness and hardenability. It is often subjected to creep–fatigue cyclic loading in service environments.

Influence of Moisture on the Shakedown Behavior of Fine Soils for Sustainable Railway Subballast Layers

open access: yesInfrastructures
This study investigates the influence of moisture on the mechanical behavior of fine soil mixtures from the São Luís region, applied as subballast layers in railway track structures. Two samples were analyzed: a non-lateritic sandy soil (NA’, AM03) and a

Plastic behavior and shakedown limit of defected pressurized pipe under cyclic bending moment

open access: yesJournal of Engineering and Applied Science
Pipelines subjected to thermal or mechanical loads may fail due to plastic strain accumulation which leads to ratcheting. In this research, cyclic plastic behavior and shakedown limit are investigated experimentally and numerically for a defected ...

Formulation of plastic strain distribution derived from long-distance travel of temperature distribution based on residual stress required for elastic shakedown behavior

open access: yesMechanical Engineering Journal, 2021
In an experimental study that simulated a fast breeder reactor (FBR) vessel near the coolant surface, it was reported that the long distance travel of temperature distribution causes a new type of thermal ratcheting, even in the absence of primary stress.

Investigation on shakedown response-behavior of thawed subgrade soils under long-term traffic loading

open access: yesFrontiers in Earth Science
The shakedown state of the subgrade is crucial for the sustainable design and long-term stability evaluation of pavement structures. In order to characterize the plastic deformation and shakedown behavior of subgrade soil in seasonal frozen regions ...

Simulation of Shakedown Behavior in Pavement’s Granular Layer [PDF]

open access: yesInternational Journal of Engineering and Technology, 2015
While in the design of flexible pavement the significance of asphalt layers is understood, the role of granular layers supporting the asphalt layers should not be underestimated. The behavior of granular layers used in base, sub-base or subgrade layer of flexible pavement is complicated due to nonlinear elastoplastic response of materials subjected to ...

Simulation of Shakedown Behavior for Flexible Pavement’s Unbound Granular Layer [PDF]

open access: yesAirfield and Highway Pavements 2015, 2015
Full-depth asphalt concrete pavements are generally designed to control fatigue cracking and reduce potential rutting when subjected to repeated heavy traffic loads. A particularly interesting question is whether a limit load exists below which excitation shakedown in the sense that the granular layer does not accumulate further deformation.
