Why 3D Optical Extensometer?


  • Prevention of measurement distortion due to out-of-plane displacement, which is not prevented by the test rig sufficiently

  • Accurate measurement and determination of Poisson's ratio of thin samples susceptible to tilting (composites, metal sheets, fabrics)

  • Control of 3D movement of measured samples and adjacent parts (sample clamping system, test rig frame, etc.)

  • Identification of sample cracking, bending or buckling

  • Identification of non-symmetric thermal expansion deformations

  • Identification and validation of actual sample deformations in 3D

  • Test rig sample loading issues, test rig set-up, test rig adjustment
