Thermal activation of fatigue crack growth: analysing the mechanisms of fatigue crack propagation in superalloys
A method for deriving apparent activation energies, Eapp, for fatigue crack growth (FCG) is presented. It is shown how these Eapp values can be used to analyse the main underlying mechanism causing the progression of the crack. The Eapp values for fatigue crack growth in air and vacuum, and with and without a dwell are obtained for a range of Ni based superalloys for turbine disc applications. ...

the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولCharacterization of a fracture specimen for crack growth in epoxy due to thermal fatigue
Finite element simulations are carried out to characterize a new fracture specimen, consisting of an outer circular epoxy ring bonded to an inner circular invar plate for accelerated thermal fatigue testing. Radial cracks are introduced in the epoxy ring. The growth of these radial cracks is correlated to the applied energy release rate G. We studied the dependence of G on the crack length, the...
متن کاملElectronic pilot-activity monitor: a countermeasure against fatigue on long-haul flights.
BACKGROUND Previous studies have shown frequent reductions in aircrew alertness during long-haul flights, even during the critical descent phase. Recommended countermeasures include alternation of crew activity with rest, such as cockpit napping. However, a method of monitoring the alertness level of the active and napping pilots should be considered. METHODS The Electronic Pilot-Activity Mon...
متن کاملFatigue of Yttria-Stabilized Zirconia: II, Crack Propagation, Fatigue Striations, and Short-Crack Behavior
Fatigue crack propagation in 3Y-TZP was investigated using controlled surface flaws. A unique growth law strongly dependent on the maximum stress intensity factor and quadratically dependent on the amplitude of the range of stress intensity factor was established. This growth law was found to apply for both surface flaws and internal flaws and could be used to predict fatigue lifetime. The pres...
