Viscoelastic Models Summary:
- Maxwell Model (Series): Continuous deformation path under constant stress $\rightarrow$ Behaves like a Viscoelastic Fluid.
- Kelvin-Voigt Model (Parallel): The internal spring caps maximum deformation and enables full shape recovery $\rightarrow$ Behaves like a Viscoelastic Solid.
