Fatigue life prediction of notched components under size effect using stress gradient-based approach

International Journal of Fracture, 2021
Notch and size effects show vital influence on fatigue performance of engineering components, which deserve particular attention for ensuring their structural integrity and reliability. In this study, the influences of size effect and stress gradient on effective stress as well as fatigue life were studied.

Non-local stress gradient approach for multiaxial fatigue of defective material

Computational Materials Science, 2008
Abstract The fatigue crack initiation from a surface defect is analysed by means of a new attempt based on multiscale reduction of the stress distribution along the potential crack initiation plane. The reduction is performed by averaging process for shear and normal stresses over two critical areas (multiscale concept). The Matake multiaxial fatigue

Oxidative stress in birds along a NOx and urbanisation gradient: An interspecific approach

Science of The Total Environment, 2018
Urbanisation is regarded as one of the most threatening global issues for wildlife, however, measuring its impact is not always straight forward. Oxidative stress physiology has been suggested to be a useful biomarker of health and therefore, a potentially important indicator of the impact that urban environmental stressors, especially air pollution ...
