Hace 4 días · Accurately assessing the fatigue performance of components is the key to ensuring structural integrity and reliability, but there is a lack of fatigue life prediction methods that effectively couple the stress gradient effect, the non-proportional additional strengthening effect, and the size effect. Accordingly, a fatigue life prediction model for notched specimens under multiaxial loading is ...
Hace 5 días · Common studies on entangled metallic wire material (EMWM) lack exploration of the material’s electrical conductivity. This paper focuses on the dynamic mechanical properties, electrical conductivity and fatigue properties of Beryllium bronze alloy wrapped wire material (QBe2-EMWM) with excellent electrical conductivity.
Hace 5 días · Corrosion fatigue (CF) [] has been a topic of research since the early 20th century.The relevance of this phenomenon is mostly associated with catastrophic cases, where corrosion and static or fatigue loading are responsible for failures [].For this reason, the prediction of component service life under the joint actions of mechanical loading and harmful environments is a significant challenge ...
Hace 5 días · Traditional ACSR overhead wires, which consist of a high-strength steel core and several layers of aluminium wires, are currently the most popular overhead line conductor (OHL) design globally. Operating conditions, particularly operating under varying stresses from Karman vortices, lead to the fatigue cracking of wires of the outer layer, followed by wires of the inner layers.
Hace 5 días · Possible mechanisms of stress corrosion cracking and corrosion fatigue in aluminum alloys, such as anodic dissolution and/or interaction with hydrogen, are considered.
Hace 5 días · This pressurization process results in considerable stress on the metallic frame and wings of the aircraft, causing metal fatigue. Over thousands of flight hours, the metal fatigue can reach dangerous levels, potentially causing a fatal accident.
The evidence was definitively able to cite that as the issue. The repairs from 22 years earlier did not completely cover the originally damaged area. As a result, the metal from the original issue continued to fatigue and eventually failed catastrophically. Check out the link to Admiral Cloudbergs write up.
