Photoelasticity is the best strategy which helps to measure the smoothness of the material distribution and explains the material equality throughout the bottle where it becomes unmanageable to understand the properties of the material. This strategy is completely different from the systematic way of measuring the stress distribution in the quality of the material. This procedure offers an extremely precise test result that measures the particular level of stress even under unexpected endurances in the material. It is the best device which is used to verify the critical point of stress in a material and used to measure the factor of stress concentration in an irregular manner.
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.
