We present a toy-brick based tabletop tensometer for research and education.
What’s so great about it?
Easy to make and use
- LEGO typical instructions make building the frame very easy
- All building instructions laid out on this website
- All parts are common and available from large distributors
- In total the TTT can be built for around 700 EUR – significantly cheaper than a commercial solution
- Easy to extend
- Simple measurement solutions
- A full graphic UI programmed in LabView controls the whole setup and analyzes the data
- Measurement of stress/strain and resistance/strain progression
- Evaluation of static material properties (Young’s modulus, Tear strength, Fracture…)
- If you don’t need it any more, tear it apart and construct something even more awesome!
Key Parameters and Accuracy
- Stretching velocity: 50-1300um/s
- Tensile Force: +-10N, +-50N with an accuracy of 30mN and 150mN respectively
- Resistance: 6 measurement ranges in order of magnitude from 0-1MOhm with and accuracy of 0.1% of the selected range
- Sledge travelling distance: 30mm with an measurement accuracy of 100um
