Extremely-low-cycle fatigue behaviors of Cu and Cu-Al alloys: Damage mechanisms and life prediction. Acta Mater 2015;83:341-356.Shao C W, Zhang P, Liu R, et al. Low-cycle and extremely-low- cycle fatigue behaviors of high-Mn austenitic TRIP/TWIP alloys: Property evaluation, damage ...
A study has been made of the effect of repeated annealing on the micro-fracture processes and on the characteristics of low cycle fatigue life of low carbon steel having fine- and coarse-grained microstructures. It was found that repeated annealing has a beneficial effect of suppressing the ...
In the nanomagnets that switch, compression always drives the magnetization away from its pre-stress state and tension always brings it back to the pre-stress state. Unfortunately, we cannot cycle the stress too many times to assess the endurance since the piezoelectric substrate develops fatigue ...

It shall be mentioned, that the setup of the deployment test should elaborate a one-time deployment in tissue-like environments and therefore does not investigate influences of fatigue, damage or imperfections which are to be investigated in follow-up studies. Results and Discussion Packaging ...
solutions; 3) decrosslinking or dissociation of CS physical networks dissipates energy effi ciently and therefore signifi cantly toughens DN hydrogels; 4) the fast reorganization of reversible CS physical networks endows DN hydrogels rapid self-recovery capacity and excellent fatigue resistance ...
hot days when people dehydrate more easily lead to sodium potassium imbalance. Celery can help people relax bowel, regulating sodium and potassium balance. Effect of vitamins on human skin, nervous system and appetite, if the body lacks vitamin B2, it is easy to cause fatigue and oral ulcer....
hysteresis energyfractureCyclic material tests in the low and extremely low cycle fatigue regime were carried out to study the properties of structural carbon steel and stainless steel. A total of 62 experiments were performed in cyclic axial and bending configurations, with strain amplitudes up to ...
From the experimental result on the extremely low cycle fatigue fracture of the cylindrical specimen (SR295 and SS400, G.L.=2.5D=28.25mm), taking large plastic amplitude into consideration, it becomes clear that the hysteresis loop loses its symmetricity. The cumulative damage energy hypothesis ...
Extremely-low-cycle fatigueHysteresis energyDamage mechanismFatigue lifeThe cyclic deformation and damage behaviors of the Fe–Mn and Fe–Mn–C TRIP/TWIP steels are comprehensively studied in a wide range of strain amplitude (from 0.3% to 8.0%). It is found that with increasing C content, the...
