Photoelastic Materials Coating Materials The Photolastic Division of Vishay Measurements Group, Inc. manufactures the widest range of photoelastic coating materials available. All of the materials are produced in an environmentally controlled "clean room" to ensure highest quality. Sheets for Flat Parts Pre-manufactured sheets from 10 X 10 in (254 X 254 mm) to 20 X 30 in (508X 762 mm). Coatings for Contoured Parts Liquid materials for making plastic coatings for structures with complex contours that cannot be satisfactorily coated with flat sheets. Adhesives Selection of the proper adhesives for use with the various photoelastic coatings. Detailed specifications for these materials are given in Bulletin S-116, PhotoStress Materials. In addition to the hypertext version incorporated into the Products Section of the Interactive Guide to PhotoStress , copies are available upon request by contacting the Vishay Measurements Group office or regional sales representative serving your area. Application Kits Specially designed application kits simplify the process of preparing and applying the PhotoStress ® plastic to the surface of the test part. Model 011 Coating Application & Calibration Kit Contains materials for preparation and calibration of the coating prior to bonding to the surface of the test part. Model 012 Sheet Casting Kit Contains supplies for casting plastic sheets for contour forming to complex-shaped surfaces. Model 013 Surface Preparation Kit Contains hardware for preparing the surface of the test part to accept the photoelastic coating. Detailed specifications for these materials are given in Bulletin S-134, PhotoStress Instruments. In addition to the hypertext version incorporated into the Products Section of the Interactive Guide to PhotoStress , copies are available upon request by contacting the Vishay Measurements Group office or regional sales representative serving your area. Model Materials Photoelastic model materials are offered in three forms: (1) Sheets, (2) Liquids for casting, and (3) Precast Blocks and Rounds ready for machining. Some of the prime characteristics essential to the success of two- and three-dimensional photoelastic model analysis that are found in these materials are: Easy machinability Excellent transparency Very low time-edge effect High sensitivity Two-Dimensional Model Analysis Sheet material for two-dimensional plane-stress model analysis is available in various sizes, thicknesses, and stiffness (modulus of elasticity). Three-Dimensional Model Analysis Materials for three-dimensional model analysis (stress-freezing) are supplied in liquid form for casting, and as pre-cast sheets, blocks, and rounds ready for machining. It is supplied "as cast", and the surface is unfinished. The material is fully cured and uniform in mechanical and optical properties. Detailed specifications for these materials are given in Bulletin S-116, PhotoStress Materials.
