These interactive notebooks were developed by Leif Rune Hellevik (NTNU, Faculty of Engineering)
to support teaching and exploration of linear viscoelastic behavior in materials such as polymers and biological tissues.
They form part of a pedagogical module introducing students to creep, stress relaxation, and modeling of time-dependent material response using the classical Maxwell and Kelvin–Voigt models.
All notebooks are designed for use directly in Google Colab and JupyterLab, with interactive sliders for material parameters.
They can be freely reused for teaching and learning purposes with appropriate attribution.
| Launch the full module | |
- Click a Colab badge above to open the notebook in your browser.
- Choose Runtime → Run all to initialize the interactive widgets.
- Use the sliders to explore how the material parameters affect:
- Creep (strain response to constant stress)
- Stress relaxation (stress decay under constant strain)
Each student runs an independent Colab session — no installation needed.
