Photoelastic effect
Purpose of the experiment and related subjects:
Observe the three distribution pattern of photo-elastic material changing into anisotropic from isotropic caused by force.
Distinguish the isclinic line and the different line.
Using 1/4 wave palta to cancle isoclinic line.
Using dedicated stress analysis software to analyze the stress(optional).
Features of the instruments:
Value display of the pressure.
Light source: 220V,30W.
Effective limiting aperture of polaroid is Φ58mm, effective limiting aperture of 1/4 wave plate is Φ58mm.
Complete set of equipment:
