Crack initiation criteria in fretting fatigue
Wear, 1990 Abstract This paper is a description of a series of fretting fatigue tests on an Al/Cu alloy in which the contact size was varied while the other relevant parameters were held constant. The fretting fatigue life was found to be infinite below a certain critical contact width.

Analysis on Fatigue Crack Initiation and Fatigue Crack Propagation in a Gear
SMART MOVES JOURNAL IJOSCIENCE, 2017 An effective gear design balances strength, durability, reliability, size, weight and cost. Because of the advantage of gear, gearbox was used widely. But its fault also brought many losses of the production and society. It was necessary to research and analysis on the dynamical behavior of the gear system.

Fatigue Crack Initiation and Propagation [PDF]
, 2019 The resistance of metal alloys to fatigue can be classified into four major regimes: low-cycle fatigue (or short life), limited resistance (between 10^5 and 10^6 cycles), high-cycle fatigue (between 10^6 and 10^7 cycles) and gigacycle (more than10^7 cycles).

A Framework for Predicting Fatigue Crack Initiation Life in Pipelines with Girth Welds
Journal of Marine Science and EngineeringCurrent studies on fatigue crack initiation in pipelines remain relatively limited. Existing frameworks are confronted with issues including difficulties in crack monitoring and limited consideration of intragranular short-crack propagation.

ALDOA Promotes Glycolysis and NLRP3/GSDMD Pyroptosis to Accelerate ALS Progression
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is characterized by progressive motor neuron degeneration. Glycolytic dysregulation is implicated in disease progression, yet the underlying mechanisms remain unclear. This study investigates how Aldolase A (ALDOA) drives ALS progression through glycolysis‐mediated motor neuron pyroptosis.
