How the methodology of photoelasticity works?
When two rays of light go from the photoelastic material, it quickly becomes polarized and provides two directions of stress, and each of the stress experiences different refractive indexes. The change in the refractive index directly replicated the relative phase difference in the waves of two components which is known as phase retardation. Hence, the application of photoelasticity of two-dimensional planes is quite easier to analyze the thickness of the photoelasticity is compared to the dimensions of the planes. The result of photoelasticity differs depending upon the quality of the product. This can be measured easily with the help of Polariscope.
Use of Illuminator Polariscope to Judge the Photoelasticity
Illuminator polariscope is the best testing machine which is used to measure the stress distribution of PET & Preform products to measure the quality and strength of the products. The minor change in the material distribution indicates a corresponding change in the refractive index of the material which explains the lower strength of the products. Using polariscope, this kind of changes can be judged easily. Presto Stantest offers the best quality of Illuminator Polariscope, for more information on the product, call our experts.
