Reconstruction of fan blade dynamic loading prior to its fracture

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2022
To maintain the functionality of fan blades, it is important to know the distribution of dynamic stresses in the blade, their amplitude and vibration frequency. Understanding of the dynamic loading pattern will allow us to determine under what conditions

Fretting fatigue crack propagation rate under variable loading conditions [PDF]

Fracture and Structural Integrity, 2016
Fretting fatigue experiments aim to represent industrial problems and most of them endure variable loading. Being able to assess lifetime of assemblies, especially for low propagation rate conditions, is essential as experimental validation is often ...

Numerical simulation of fatigue crack propagation in heterogeneous geomaterials under varied loads using displacement discontinuity method

Journal of Rock Mechanics and Geotechnical Engineering, 2023
Heterogeneous brittle geomaterials are highly susceptible to cyclic loads. They contain inherent flaws and cracks that grow under fatigue loads and lead to failure.

Fatigue of Fillet-welded Joint Assessment by the FEA Simulation of Damage Accumulation [PDF]

Инженерно-строительный журнал, 2011
Fatigue strength evaluation of non-continuous incomplete penetration fillet-welded joints transferring stress flow by the S-N criteria incorporating the «Hot-spot stress» or «Notch-stress» approaches is dubious since the characteristic stress at the ...

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.
