The minimum value of the failure displacement ratio is observed at a crack inclination angle of α = 45◦, corresponding to approximately 72.85% of that of intact circular specimens, indicating that the damage caused by the crack is the highest at this angle. Conversely, when the crack ...
At present, system-level failure prediction mainly includes two main problems, one is to establish a suitable SHI that can accurately describe the health condition of the system, the other is to select an appropriate prediction method according to the HI to realize the failure prediction [8]. ...
