Lab Session B

Lab Session B

 

Part I:  Compression test on a circular disc  (Brazilian disk setup) (duration:1h30)

Objectives

  • Perform compression tensile test in elastic range. Record a few images during the loading.
  • Compare to analytical solution

Competencies

  • resolution vs. spatial resolution in practice

Part II: Disk in inflation: stereo image correlation (duration:1h30)

Objectives

  • Operate calibration with target that fits field of view. Check whether the calibration is done well via epipolar constraint and MatchID calibration platform
  • Validate the cross camera matching by reconstructing the initial shape of undeformed specimen. As such, the calibration, speckle pattern and noise can be checked before the real test takes place.
  • circular plate clamped at its edges and submitted to a uniform pressure at the bottom surface. For small deformations there is a closed form solution.  Images captured at larger deformations give then a qualitative view of the deformation process.

Competencies

  •  The trainee knows how to perform a good calibration
  •  The trainee is familiar with setting up a stereovision system and perform the synchronized image registration
