ConstitutiveModels.AbstractMotion — TypeConstitutiveModels.IsochoricUniaxialStress — TypeProvides an analytic motion for uniaxial stress assuming perfect incompressibility.
This is
\[\mathbf{F} = \begin{bmatrix} \lambda & 0 & 0 \\ 0 & \frac{1}{\sqrt{\lambda}} & 0 \\ 0 & 0 & \frac{1}{\sqrt{\lambda}} \end{bmatrix}\]
ConstitutiveModels.SimpleMotion — TypeConstitutiveModels.SimpleShear — TypeProvides an analytic motion for simple shear.
This is
\[\mathbf{F} = \begin{bmatrix} 1 & \gamma & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{bmatrix}\]
ConstitutiveModels.UniaxialStrain — TypeProvides an analytic motion for uniaxial strain
This is
\[\mathbf{F} = \begin{bmatrix} \lambda & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{bmatrix}\]
