A Fatigue Life Prediction Method Based on Strain Intensity Factor [PDF]

open access: yesMaterials, 2017
In this paper, a strain-intensity-factor-based method is proposed to calculate the fatigue crack growth under the fully reversed loading condition. A theoretical analysis is conducted in detail to demonstrate that the strain intensity factor is likely to be a better driving parameter correlated with the fatigue crack growth rate than the stress ...

Investigation of Piezoelectric Patches Placement According to the Strain Intensity [PDF]

open access: yesApplied Engineering Letters : Journal of Engineering and Applied Sciences, 2020
In active vibration control of the smart structures, the dynamic characteristics directly affect the damping performance; also, the actuators are the important element for the vibration reduction. Therefore, the optimal placement of the actuators/sensors on the structure is the key parameter to enhance the control performance.
