Failure modes of silicon nitride rolling elements with ring crack defects [PDF]
High quality silicon nitride ceramics have shown some advantages for rolling element bearing applications. In particular hybrid bearings (silicon nitride rolling elements and steel races) have the ability to withstand high loads, severe environments ...

Simulation of fatigue behaviour in fusion welded 2024-T351 [PDF]
, 2004 A model has been developed to predict short crack fatigue life in the fusion zone of Metal Inert Gas (MIG) welded 2024-T351, based on the observed propensity for complex, multiple cracking processes in this region.

A fatigue multi-site cracks model using coalescence, short and long crack growth laws, for anodized aluminum alloys [PDF]
, 2010 It has been shown that decrease of the fatigue life of aluminium alloys treated with anodization can be explained by the degradation of surface condition due to pickling.

Micromechanisms of short fatigue crack growth in an Al-Si piston alloy [PDF]
, 2014 The short fatigue crack growth behaviour of a model cast aluminium piston alloy has been investigated. This has been achieved using a combination of fatigue crack replication methods at various intervals during fatigue testing and post-mortem analysis of

A predictive fatigue life model for anodized 7050 aluminium alloy [PDF]
, 2013 The objective of this study is to predict fatigue life of anodized 7050 aluminum alloy specimens. In the case of anodized 7050-T7451 alloy, fractographic observations of fatigue tested specimens showed that pickling pits were the predominant sites for ...

Fibers reinforcement of the fissured clayey soil by desiccation
Magazine of Civil Engineering, 2022 The cracks caused by desiccation induce rapid failures as rapid shallow landslides in stiff and fragile clayey soils. Several environmental structures such as landfill liners and road embankments are often constructed by compaction of a series of soil ...

Interstratal dewatering origin for polygonal patterns of sand-filled cracks: a case study from late Proterozoic metasediments of Islay, Scotland [PDF]
, 1998 Sand-filled cracks from the Lower Fine-grained Quartzite of Dalradian (late Proterozoic) age on the Island of Islay, western Scotland, may be divided into two main types, both of which form orthogonal and non-orthogonal closed patterns on bedding ...

On the transition of short cracks into long fatigue cracks in reactor pressure vessel steels
MATEC Web of Conferences, 2018 Short fatigue cracks, having dimension less than 1 mm, propagate at much faster rates (da/dN) even at lower stress intensity factor range (da/dN) as compared to the threshold stress intensity factor range obtained from long fatigue crack growth studies ...

Comparison of Inductive Thermography and Computer Tomography Results for Short Surface Cracks
Engineering Proceedings, 2023 Inductive thermography is a non-destructive testing method, whereby the workpiece to be inspected is slightly heated by a short inductive heating pulse. An infrared camera records the surface temperature during and after the heating pulse.
