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
