Implementation of Gel constitutive model.
Implementation follows constitutive equation from:
VISCOELASTICITY AND POROELASTICITY IN ELASTOMERIC GELS Acta Mechanica Solida Sinica, Vol. 25, No. 5, Yuhang Hu Zhigang Suo
Note1: Following implementation is tailored for large strain analysis, however in current version the engineering strain is used, i.e. assuming small deformation. Moreover calculation of solvent flux and other physical quantities is with assumption that those values are nonlinear.
Note2: Basic implementation is with linear constitutive equations, however adding nonlinearities to model should be simple, since all tangent matrices are calculated using adloc-c.
System of equations of equations in the form is assembled:
\[ \left[ \begin{array}{ccc} \mathbf{K}_{xx} & \mathbf{K}_{x\mu} & \mathbf{K}_{x\hat{\varepsilon}} \\ \mathbf{K}_{\mu x} & \mathbf{K}_{\mu \mu} & \mathbf{K}_{\mu \hat{\varepsilon}} \\ \mathbf{K}_{\hat{\varepsilon} x} & \mathbf{K}_{\hat{\varepsilon} \mu} & \mathbf{K}_{\hat{\varepsilon} \hat{\varepsilon}} \end{array} \right] \left[ \begin{array}{c} \mathbf{q}_{x}\\ \mathbf{q}_{\mu}\\ \mathbf{q}_{\hat{\varepsilon}} \end{array} \right] = \left[ \begin{array}{l} \mathbf{f}^\textrm{internal}_{x}\\ \mathbf{f}^V_{\mu}+\mathbf{f}^J_{\mu}\\ \mathbf{r}_{\hat{\varepsilon}} \end{array} \right] \]
