Prediction of growth rate of short fatigue cracks.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1987 A method based on crack closure was proposed to predict the growth rate of short fatigue cracks in either smooth specimens or notched specimens. The material properties used in this prediction were the growth behavior of long cracks and the fatigue limit of smooth specimens.

Influence of High Pressure Drop Rates on Fatigue Crack Growth
Chemical Engineering & Technology, 2022 AbstractHydraulic components in mobile machines are subjected to varying conditions and loads, which limit their lifetime. In particular, high pressure drop rates are suspected to increase fatigue crack growth rates. Existing studies on the fluid‐structure interaction inside fatigue cracks during fast pressure drops do not explain increased crack ...

A numerical study of crack shielding and deflection under extensive plasticity [PDF]
, 2009 Experimentally observed crack deflection events in multi-layered material systems, occurring even under pure mode-I loading, are here simulated and explained through elasto-plastic finite element modelling.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

Study on the short fatigue crack initiation and propagation behavior of 42CrMo
Advances in Mechanical Engineering, 2022 A micro-tensile fatigue test of 42CrMo alloy steel was carried out. The result shows that the crack initiation and propagation of the material could be characterized with randomness and localization.

The Influence of In-Plane Constraints on Fatigue Crack Growth Rate
Advances in Science and Technology Research JournalThe geometry of structural members can influence the fatigue crack growth rate. In the paper, the T-stress depending on the element's geometry is used to quantify the effect of geometry on the fatigue crack growth rate. A series of fatigue tests on three-point bending specimens with different initial crack lengths were conducted.

Prominent Movement Disorders in RNU2‐2‐Related Spliceosomopathy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Pediatric movement disorders often overlap with neurodevelopmental diseases, suggesting shared molecular mechanisms. Variants in small nuclear RNA (snRNA) genes encoding spliceosome components have recently been associated with neurodevelopmental disorders, termed “RNUopathies.” We analyzed genome sequencing data from 14 patients with ...
