Basics
- Part of the Open Source Laboratory Construction Set
- An Open Source "Universal Tester"
- Used to measure the Compressive Strength , Shear Strength , and Tensile Strength of any material made into the standard shape (usually a bar or hook
- Uses load cells, but the early versions could use Hook Style Scales
- Is almost essential if we start making any materials to provide hard, consistent evidence of material properties, especially for metals, and plastics
- Can also be used to test various weld techniques (On a purpose built small destructive test sample however for proof of concept, it doesn't replace a X-Ray Based Weld Inspection Device
- Can also test the "tackyness" / cohesion+adhesion of various glues, and greases
Industry Standards
Existing Open Source Designs
FreeLoader
Testbot
- A ~300 USD machine
- Instructable on the device
- The Youtube Video on the Device
CNC Kitchen
- Supposeldy ~110 USD
- Uses a diy optical Extensometer
- The Youtube Video on the Device
Minimum Viable Product
- Perhaps a low strength, and "it will break anything" version
- The former for education, and plastic workflows (as well as low level tests etc)
- The latter as a direct substitute for high end machines
Basic Design
- Can Universal Axis develop enough torque? would a gearbox, and/or "stacking" multiple axis work?
- If not that, the Open Source Hydraulic Cylendar perhaps?
