The impact of mechanical fatigue on load-bearing metallic components and structures is
highly significant, encompassing economy, environment and safety aspects. For nearly 200 …

Fretting fatigue is a fatigue damage process that occurs when two surfaces in contact with
each other are subjected to relative micro-slip, causing a reduced fatigue life with respect to …

Contact problems are central to Solid Mechanics, because contact is the principal method of
applying loads to a deformable body and the resulting stress concentration is often the most …

The fretting behaviour of a Ti–6Al–4V alloy was studied in a plain cylinder/plane contact
configuration under ambient conditions. Inspired by a fretting map approach, a global …

In this study, the fatigue behaviors of GH4169 superalloy, which possessed a gradient
nanostructure layer introduced by an ultrasonic surface rolling process (USRP) and …

The effect of crystal orientation on fretting fatigue induced crack initiation and dislocation
distribution is studied by in-situ SEM observation and electron back-scattered diffraction …

The proposed deflecting abrasive waterjet peening (DAWJP) process can be used for
surface strengthening of metallic parts with confined space features, which has great …

在航空航天, 石油化工与能源动力等诸多领域, 关键机械装备的长寿命高可靠运行需求与其严苛
服役环境之间的矛盾日益凸显. 一方面, 基于单一损伤或失效模式的寿命设计方法无法涵盖多 …

Fretting fatigue (FF) is one of the main causes of turbine blade failure. In this study, the FF
tests of a nickel-based single crystal (NBSC) superalloy treated by shot peening (SP) are …

Improving fatigue properties of engineering alloys using conventional laser shock peening
(LSP) with protective coating frequently causes surface grain subdivision, which is …
