An experimental and theoretical study is carried out to investigate the temperature evolution of Aluminum 6061 and Stainless Steel 304 specimens under cyclic fatigue load. A thermographic technique is used to measure the temperature increase of the specimen due to hysteresis heating during fatigue t

Fretting fatigue is a complex problem and therefore it has generally been necessary to determine fatigue lives experimentally. This paper describes a method that integrates wear modelling with fretting fatigue analysis to permit the prediction of the effects of material removal, due to fretting wear
Fatigue tests were carried out on tensile-shear spot-welded specimens under random loading; at the same time, natural frequencies at different life stages were measured. Test results were compared with that under constant amplitude loading. The relationship between damage and natural frequency chang
The crack coalescence in some materials is known to make influence on the failure life significantly in low cycle fatigue as well as corrosion fatigue. A model was proposed to simulate crack linking during fatigue process. The crack distribution observed experimentally was idealized by a two-dimensi
In this paper, two fatigue lifetime prediction models are tested on TiAl intermetallic using results from uniaxial low-cycle fatigue tests. Both assessments are based on dissipated energy but one of them considers a hydrostatic pressure correction. This work allows to confirm, on this kind of materi
