The material surface condition has a predominant effect on high-cycle fatigue
and less important for low-cycle fatigue.
Electromagnetic resonance testing machine for axial dynamic load testing for high-cycle fatigue
, crack propagation velocity measurement and predcyklovEivEinE[degrees] crack at the ct samples.
The algorithm considers the redistribution of stresses in reinforced concrete columns subjected to high-cycle fatigue
The dividing line between the low-cycle and the high-cycle fatigue
is determined at the point where the fatigue curve, plotted in the natural coordinates, goes from convex to concave.
Some specific topics include laser shock processing of Ni-base supperalloy and high-cycle fatigue
properties, the effect of square wave AC parameters on weld forming performance, the dissolution mechanism of copper weld brazing with Cu-based brazing alloys, and a morphological filtering algorithm for estimation of tool wear in CNC milling machining.
However, their application to the field of industrial machines requires further investigation, since the steel handling machines operate in the zone of high-cycle fatigue
under the plan, samples were cut across the rolling, but according to Standard GOST 7564-97 ([?
General Electric, Embraer The US FAA has proposed an airworthiness directive for certain General Electric CF34-10 fan rotor spinners and their supports to prevent high-cycle fatigue
cracking that could lead to separation of the fan rotor spinner assembly and uncontained failure.
Brent Carey, a graduate student in Ajayan's lab, found the interesting property while testing the high-cycle fatigue
properties of a composite he made by infiltrating a forest of vertically aligned, multiwalled nanotubes with polydimethylsiloxane (PDMS), an inert, rubbery polymer.
4a) and the internal layer with the developed coarse-grained [UPSILON]'-phase of the sharp angle form which, playing the role of notches, may reduce the strength of the metal of the lock in high-cycle fatigue
The 42 papers include discussions of biomimetic multiphasic calcium phosphates to enhance bone regeneration, the high-cycle fatigue
evaluation of two beta-rich titanium casting alloys, understanding errors in mechanical testing results, the effects of cold work and heat treatment on the properties of nitinol wire, increasing the wettability and biocompatibility of metal implants by low-pressure plasma treatment, the electrochemical behavior of cobalt-chromium alloys, designing and developing metal-polymer film systems for flexible electrodes used in cortical mapping, and other topics.
Where we score, though, is in our extrusion process--the high cycle fatigue of an extruded shaft as we make it in titanium 834, our number-one high-temperature titanium material that gives at least a 30% gain in high-cycle fatigue
strength compared to the same material with the hot-roll process.
A microstructural model for predicting high-cycle fatigue
life of steels.
