Relying on the ASTM D412 testing standards, the materials are characterised tensile testing of dumbell shaped specimens. CAD file for the respective moulds are provided here.

Fabrication of the Specimen

Elastomer_Fabrication_Step

  1. Mixing of the two parts
  2. de-airing the mixture,
  3. pouring into molds
  4. curing for 24h,
  5. measuring the dimensions,
  6. inspecting the quality.

Constitutive Model Curve Fitting Script

An open source online app is available to fit experimental tensile stress-strain data :

Written in Python, the code is availlable in the repository under the folder: https://github.com/LucMarechal/Soft-Robotics-Materials/tree/master/Python%20script%20fitting%20of%20hyperelastic%20constitutive%20models
