| Research Abstract |
Basic study on ultrasonic welding, which is one of solid state bonding technique, has been performed using motion analysis by optical measurement. Relative motion of weld tool, with respect to the working materials, during ultrasonic welding tests are analyzed using the digital correlation method. The dynamic behavior of material during the ultrasonic welding has been evaluate applying the result of motion analysis to the visualization of strain field. It has been clarified that the relative motion between the weld tool and work material strongly affect the microstructure development at the weld interface.
