Dynamic Stress Analysis (Stroboscopic Effect)
For PhotoStress analysis, a reflection polariscope is used to observe and measure the surface strains on the photoelastically coated test part. The PhotoStress Plus LF/Z-2 Reflection Polariscope covers a wide range of strain measurement capabilities. For instance, measurements made on small parts or in regions of high stress concentration are both easier and more accurate when zooming in with the digital video camera supplied with the polariscope. And the standard light source used for static measurements is readily replaceable with an optimal stroboscopic light accessory for cyclical dynamic measurements.
