Hace 5 días · Besides, the fatigue damage expansion rate of cold-rolled steel sheets is less than the standard value. Through further discussion, it is noticed that metal grade has little influence on the fatigue performance, while thickness has a significantly positive influence on the shear resistance and fatigue performance.
16 de abr. de 2024 · The stress-controlled low-high block loading of low cycle fatigue (LCF) at high tem... Nonlinear fatigue life prediction model based on isodamage curve considering two‐block loading - Yun - Fatigue & Fracture of Engineering Materials & Structures - Wiley Online Library
Hace 1 día · This study entails comprehensive analyses of the temperature dependence of tensile properties and strain-controlled low cycle fatigue behavior exhibited by ASTM A302 grade C steel, which is specifically a manganese-molybdenum-nickel alloy. Tensile strength at elevated temperature ranges from 400 to 428 °C closely approximates those measured under ambient conditions, while the ductility ...
Hace 1 día · Ultrasonic fatigue testing (USFT) is a time-efficient method for evaluation of the fatigue limit of metallic alloys in a high and very high cycle range. Propagation of a final crack at the very end of the fatigue life can be clearly detected by USFT parameters and monitoring techniques.

26 de abr. de 2024 · This work employs the Birnbaum–Saunders distribution to model the fatigue-life of metallic materials under cyclic loading and compares it with the normal distribution. Fatigue-limit models are fitted to three datasets of unnotched specimens of 75S-T6 aluminum alloys and carbon laminate with different loading types.
23 de abr. de 2024 · Metals: Susceptible to corrosion and fatigue. Plastics: May degrade over time, especially when exposed to UV light or chemicals. Composites: Can delaminate or suffer from internal stresses. Human Components. Training and oversight can reduce the risk of human error, which is often a significant component in failure.
