The fatigue contrast tests of unload longitudinal direction cer joints as original welded and treated by ultrasonic peening of Q235B in various stress ratio are
A new time-domain analysis method that uses second generation wavelet transform (SGWT) for weak fault feature extraction is proposed. To extract incipient fault
Based on a lot of numerical solutions to the problems of the thermal non-Newtonian elastohydrodynamic lubrication and some fatigue tests with rollers, the lubri
