In this capacity, he will be responsible for overseeing the operation of the Fracture Mechanics Test Lab and handling proposals for fatigue crack growth, fracture toughness, high-cycle fatigue and other testing performed by the department.
As a result, the fuel pump welds in these vehicles may be susceptible to high-cycle fatigue fractures that could cause the fuel pump to move relative to its mounting flange, resulting in eventual loss of the sealing integrity of the cam cover or the fuel lines and an oil or fuel leak, increasing the risk of fire.

As stated earlier, for the high-cycle fatigue, the total damage is a sum of the fatigue and static damage components.
So far, studies on high-cycle fatigue behavior of GFRP based on full-scale components are found lacking.

The critical locations in the lower sheets for initiation of high-cycle fatigue failure are marked by "HCF Fracture" in the figures.
With this method, the elastic strain-life curve according to [22] is divided into three different parts describing the single fatigue tests and thus the material behavior in the low-cycle, the high-cycle and the very high-cycle fatigue regimes much better.
In this work, Q345 and QSTE700 steels two common materials used for making H-shaped frame beams were employed in high-cycle fatigue tests to study the fatigue characteristics of H-type automobile frame girders.
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.
