TRACTION 3D : Direct analysis of material's necking area by two cameras

Description

This system must be coupled to a in-situ traction device, to observe the behavior of the sample drawn during any phase traction .
The software analyses images and can achieve a control imaging devices (and/or traction machine) according to the course of the trial.

Benefits :

  • Information on the 3D evolution of materials upon drawing.
  • Analysis of complex systems during anisotropic deformation.
  • Direct measurement of a necking area.
  • Monitoring the evolution of tears.
  • Follow-up of very large deformations (eg on plastic films).
  • No requirement of sample marking or any other surface modification.
