Video extensometers are advanced, non-contact measurement devices designed to accurately determine the deformation and strain characteristics of materials during mechanical testing. Utilizing high-resolution digital cameras and sophisticated image processing algorithms, these instruments track the displacement of specific markers or the natural texture on a specimen's surface throughout testing. This non-invasive approach ensures precise strain measurements without influencing the specimen's behavior, making video extensometers particularly suitable for testing delicate, soft, or high-elongation materials.
These devices are versatile and can be employed in various testing scenarios, including tensile, compression, bending, and torsion tests. Their adaptability extends to different environmental conditions, as they can be integrated with temperature chambers and fluid baths to assess material performance under diverse circumstances.
