24 de sept. de 2020 · Aviation Metal Fatigue. Metal fatigue in aircraft is a common occurrence due to the cyclical nature of pressure and stress on aircraft parts and components. Over time small cracks can increase in size and scope, where metal fatigue can become a contributing factor to mechanical and structural failure. Pressure, atmospheric exposure, and general ...
疲劳是一个比较古老的话题，但对于结构安全又十分重要。最近在学习疲劳损伤相关的知识，一些概念在今后的学习工作中也可能会有所应用，因此做一些记录。主要参考的教材是《Metal Fatigue in Engineering》 [1]和《…
11 de sept. de 2023 · Corrosion fatigue” refers to the response of metal materials to the combined effect of a corrosive medium and cyclic loads, typically in an aqueous environment. Different environmental conditions, such as corrosion fatigue, low temperature fatigue, high temperature fatigue, and varying air pressure and humidity, can all affect the fatigue behavior of materials.

2 de feb. de 2020 · Each time the metal deforms and then returns to its original shape, more molecular faults occur. After many deformations, there are so many molecular faults that the metal cracks. When enough cracks form for them to merge, irreversible metal fatigue occurs. Metal strain is a major challenge for engineers.
21 de nov. de 2019 · Posted: November 21, 2019. Metal fatigue is one of the subtlest types of metal failures, and one of the most dangerous. Although metal failure can occur from excessive tensile loads, shear loads and impact loads, to name a few, metal fatigue is a failure type that can go unnoticed right up until the point when it is too late.
1 de oct. de 2022 · Fatigue analysis methods considering stress gradient effect. The notched components and structural details including holes, shoulders, grooves, etc. are indispensable for satisfying special functions. In metal fatigue analysis, the notch and size effects are in the top priority for reliability assessment of engineering structures.
