Precipitation-hardened steel exhibits specific characteristics due to the punching process
that deteriorates its strength. To investigate these characteristics, fatigue tests were …

To predict the fatigue limit with a mechanically long crack under mixed modes based on the
fracture mechanics, fatigue tests were conducted with an inclined notch. As a result, damage …

To quantify the material and mechanical effects on the damage accumulation (DA) mode of
fatigue crack propagation (FCP), a crystal plasticity finite element method was used in a …

The fatigue properties of martensitic steels are highly microstructure-dependent, preventing
the use of fatigue design criteria for ordinary steels, thus hindering their widespread …

The appearance of strain localization (SL) in front of the crack tip is a factor that promotes
transition toward the fatigue crack extension mode. Therefore, to predict fatigue crack …

Spot segregation and banded defect are unsolved technical problems of high-quality steel.
In this paper, spot segregation of different sizes and irregular morphology were found in …

The transition point of the crack length to a microstructurally small crack is necessary for
predicting crack extension behavior. The conventional criterion is the crack length smaller …

Our previous study demonstrated that, in a cracked single‐crystal subjected to remote
tensile stress, the interactions among material behavior, strain localization, mechanical …

Failure in a turbo-expander Tie-Bolt (stud) made of superalloy A-286 was investigated. The
evaluation of the chemical composition and tensile properties confirmed compliance with the …

With the rapid development of the wind energy industry, there is an increasing concern
about operation safety and reliability of high-strength wind turbine bolts. The aim of this …
