The effect of ultrasonic vibration on the springback and surface property for ultrasonic-assisted incremental sheet forming aluminum alloy were discussed. A series experiments established to explore symmetrical in order facilitate analysis experimental results. It is obtained that application can reduce effect. waviness feature becomes weaker with continuous increase amplitude topography tends ...

Al wire bonding, also called ultrasonic wedge-wedge bonding, is a microwelding process used extensively in the microelectronics industry for interconnections to integrated circuits. The bonding wire used is a 25 m diameter AlSi1 wire. A friction power model is used to derive the ultrasonic friction power during Al wire bonding. Auxiliary measurements include the current delivered to the ultraso...

In the present research, vibrational behavior of anisotropic protein microtubules (MTs) immersed in cytosol via Cooper–Naghdi shell model is investigated. MTs are hollow cylindrical structures in the eukaryotic cytoskeleton which surrounded by filament network. The temperature effect on vibration frequency is also taken into account by assuming temperature-dependent material properties for MTs....
