Stresscoat coatings provide a graphic picture of the distribution, direction, location, sequence and magnitude of tensile strains. The brittle coating will fracture in response to the surface strain beneath it. The coating indicates the direction and magnitude of stress within the elastic limit of the base material. The brittle-lacquer technique of experimental stress analysis relies on the failure by cracking of a layer of a brittle coating which has been applied to the surface under investigation. The coating is normally sprayed onto the surface and allowed to air- or heat-cure to attain its brittle properties. A new series of ceramic-based materials has been developed which will operate from approximately —50 to 600 F in a sensitivity range of 200 to 1800 microinches, depending on the coefficient of expansion of the steel on which the coating is applied. These ceramic brittle coatings permit experimental stress analysis on steel parts up to 600 F. When the specimen is subjected to external loads, the thin brittle coating cracks under tensile stresses. Brittle Coating Technique - Experimental Stress Analysis The principle of stress analysis involves the adherence of a thin coating (resin- or ceramic-based) brittle in nature on the surface of a specimen. When the specimen is subjected to In this paper, an attempt is made to extend in both directions the range of the stresses that can be determined using brittle coatings: (1) by sensitizing the coating to determine small stresses, and (2) by the use of a new calibration device that allows the application of very large strains.The increase in sensitivity is obtained by bathing the coating with cold water under load.
