Laser vibrometry measurements on a bowed violin are performed. A rotating disc apparatus, acting as a violin bow, is developed. It produces a continuous, long, repeatable, multi-frequency sound fro ...

Laser welded products often have to be designed and optimized for fatigue load. The most common method to characterize the fatigue strength is periodic loading of a weld for different peak loads to identify an S-N-curve. To obtain information on how

During laser welding, residual stresses are thermally induced. They can have strong impact on the fatigue behavior and fatigue life. A standardized measurement method for the fatigue crack growth rate was expanded to identify residual stress along th
