The fatigue fracture of structural details subjected to cyclic loads mostly occurs at a critical cross section with stress concentration. The welded joint is particularly dangerous location because of sinergetic harmful effects of stress concentration, tensile residual stresses, deffects, microstructural heterogeneity. Because of these reasons many methods for improving the fatigue resistance o...

UNLABELLED The dynamic loading in human body, along with the corrosive body fluid, presents a great challenge for the practical use of biodegradable magnesium implants. In this study, a high purity magnesium (99.99wt.%) and two typical promising biodegradable magnesium alloys (binary Mg-1Ca and ternary Mg-2Zn-0.2Ca) were chosen as the experimental materials. Their dynamic mechanical performance...

Vertebral fractures associated with osteoporosis are often the result of tissue damage accumulated over time. Microscopic tissue damage (microdamage) generated in vivo is believed to be a mechanically relevant aspect of bone quality that may contribute to fracture risk. Although the presence of microdamage in bone tissue has been documented, the relationship between loading, microdamage accumul...

The aim of this study is to measure the effects and relationships cyclical fatigue in scientific studies with bibliometric analysis methods field endodontics, identify main trends supported by visualization. Studies on "cyclic fatigue" endodontics were searched Web Science (WoS) Scopus academic databases 30 August 2022, including publications for 2022. Pandas Library, one Python libraries, was ...

shot peening applies a residual compressive stress field (rcsf) on the surface of parts. it also shifts “crack nucleation sites” to sub-surface locations. a nondestructive method of measuring the stresses, sin2ψ was utilized here and the stress values introduced to ansys software. for this purpose, uniform stress in all directions was applied on the con rod. loading on the rod in ansys had thre...

Cyclic compression fatigue properties of concrete are studied with the ultrasonic testing method cycling frequency 19 kHz and compared to servo-hydraulic tests performed at 60 Hz. Ultrasonic was found applicable for rapid generation very high cycle (VHCF) data concrete. Fatigue cracks can be initiated, however specimens do not rupture, since cyclic stresses decrease increase compliance in displ...

Although human dentin is known to be susceptible to failure under repetitive cyclic fatigue loading, there are few reports in the literature that reliably quantify this phenomenon. This study seeks to address the paucity of fatigue data through a systematic investigation of the effects of prolonged cyclical loading on human dentin in an environment of ambient temperature Hank's balanced salt so...
