KelvinVoigtElement

Source: models/solid_mechanics/viscoelasticity/KelvinVoigtElement.py

Stress response of a Kelvin-Voigt viscoelastic element (spring and dashpot in parallel), \(\boldsymbol{\sigma} = E \boldsymbol{\varepsilon} + \eta \dot{\boldsymbol{\varepsilon}}\), where \(E\) is the spring modulus and \(\eta\) is the dashpot viscosity.
