Fatigue & Fracture of Engineering Materials & Structures
Nickel‐based superalloys are widely utilized in aerospace, energy, and other fields for their exceptional high‐temperature and oxidation resistance. However, in engineering, components often endure over 109 cycles, causing very high cycle fatigue (VHCF ...

A damage parameter for HCF and VHCF based on hysteretic damping
International Journal of Fatigue, 2014Abstract The fatigue limit of materials, due to the improvement of fatigue life of structures and mechanical components should be extended from the traditional 106–107 cycles up to 109 and more, but with traditional testing hardware this is a difficult technical task due to the length of time needed for the completion of tests.

Estimating the fatigue behavior of welded joints in the VHCF regime
International Journal of Structural Integrity, 2012PurposeThe present work aims to deal with a very high cycle fatigue (n=109 cycles) of gas metal arc welded joints, subjected to a multiaxial and non‐proportional loading. Different design codes and recommendations can greatly reduce the analysis effort in the design of welded structures providing a suitable balance between computational accuracy and ...

VHCF test and life distribution of aluminum alloy LC4CS
International Journal of Fatigue, 2008Very high cycle fatigue (VHCF) test of 82 aluminum alloy LC4CS specimens was done by piezo-electric fatigue testing machine and fatigue life data were obtained. The obtained fatigue life data showed that the fatigue life distribution of the alloy under VHCF has a characteristic of duplex peak, which is related to the locations of fatigue crack ...

Crack initiation mechanisms in AA6082 fatigued in the VHCF-regime
International Journal of Fatigue, 2014Abstract Over the last decades research activities in the field of very high cycle fatigue (VHCF) have strongly increased. It has been shown important to distinguish between single phase inclusion free type I and multiphase type II materials. Although, considerable efforts were made, the basic understanding of the dominating deformation/damage ...
