This research work deals with the development of a methodology for the preliminary
assessment of hardness, fatigue, and crack propagation performance of plastic parts …

In this work, the short crack propagation and growth rate nonlinear behavior of an Al 6061
alloy in T6 condition, were assessed. The specimens were fatigue tested at 20 Hz in a …

Fatigue properties of S135 drill pipe steel 27CrMo under different conditions were
investigated by rotating bending fatigue test. The results show that the fatigue limit at 10 6 …

A mechanical fatigue test device was developed to perform different fatigue test in a single
machine, including: bending, torsion, rotating bending, and combined bending-torsion. The …

Fatigue crack closure phenomenon is now recognised as one of the most influential
mechanisms operating during fatigue. The crack closure effect helps explain a wide range of …

Microalloyed S355N steel plates are extensively used in bridge and high-rise building
structures. One of the factors affecting the mechanical properties is the size and morphology …

In this paper, effect of residual stresses resulting from plastic beam bending technique on
fatigue crack growth initiation was investigated on 2024 T351 aluminium alloy. The residual …
