Shakedown of bolts with a one-sided propagating crack

Journal of Civil Engineering and Management, 2002
Cyclic strains of joints may cause formation of a crack or cracks in a bolt thus changing its loading conditions. After crack appearance in a bolt it can be used if its length does not exceed a critical one.

Friction Influenced by Vibrations: A Refined Contact-Mechanics View on Lateral and Rotational Oscillations

Frontiers in Mechanical Engineering, 2020
It is known that superposed movements can lower the friction felt at the macroscale. This is well documented for in-plane and normal translatory oscillations.

On the shakedown analysis of welded pipes

, 2011
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 ...

Shakedown analysis of a composite cylinder with a cross-hole

, 2011
In this study, both the lower and upper bound shakedown limits of a closed-end composite cylinder with or without a cross-hole subject to constant internal pressure and a cyclic thermal gradient are calculated by the Linear Matching Method (LMM ...

Low cycle fatigue simulation and fatigue life prediction of multilayer coated surfaces [PDF]

, 2010
This paper focuses on the simulation of low cycle fatigue (LCF) failures in highly loaded coated surfaces subjected to mixed rolling-sliding contact in dry conditions. The development of an advanced finite element (FE) model and creation of a unique user-

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

Metals
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.
