DYNAMIC STRAIN ANALYSIS METHOD USING ONE-BEAM SHEARING MOIRE INTERFEROMETRY

  • This paper developed a new dynamic analysis method based on the principle of one beam shearing Moire interferometry.The method can be used to measure the full strain field of dynamic problems. It is characterised by simple optical arangment,excellent fringe contrast and high sensitivity, etc. Besides, as it uses a portable multiple pulsed - ruby -laser as light source,the method is particularly suitable for field measurement.In the paper, a problem of stress propagating in a rectangle is studied with the ab...
