Ultra low-cycle fatigue performance of S420 and S700 steel welded tubular X-joints
International Journal of Fatigue, 2019 The present study is motivated by the need for improving the fatigue performance of offshore wind energy structural systems. In particular, the ultra low-cycle fatigue performance of welded tubular X-joints is examined, motivated by the need of ...

Effect of Principal Direction Change on High Temperature Multiaxial Low Cycle Fatigue Lives Using Cruciform Specimen [PDF]
, 2001 Low cycle fatigue tests were carried out using crucifonn specimens of Type 304 stainless steel under multiaxial strain states at 823K. Strain paths employed in the tests were not only proportional strain histories but also severe strain histories ...

Advanced Engineering Materials, EarlyView.Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

The Effect of microstructural heterogeneities on the fatigue behaviour of 22MnB5 sheet steel [PDF]
, 2013 This work deals with the effect of heat treatment on the fatigue strength of a rear axial beam and aims to propose a methodology suitable and reliable for fatigue design.

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Advanced Engineering Materials, EarlyView.Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Low-Cycle Fatigue Behaviour of AISI 18Ni300 Maraging Steel Produced by Selective Laser Melting
, 2018 Selective laser melting has received a great deal of attention in recent years. Nevertheless, research has been mainly focused on the technical issues and their relationship with the final microstructure and monotonic properties.
