| Abstract: | The stress concentrations of structures have a large influence on fatigue strength, By means of fiber-optical and moire interference, the stress concentrations, around the closed angle in sharp V-notches, are measured. At the same time, fiber-optical takes the place of many optical componoents in moire interfrence, so the measurements become convenient, economical, stable and reliable. |
