[case] CreepBGRa

A class for computing the BGRa creep model, which reads.

\[ \dot {\mathbf{\epsilon}}^{cr}=\sqrt{\frac{3}{2}}A \mathrm{e}^{-\frac{Q}{RT}} \left(\frac{\sigma_{eff}}{\sigma_0}\right)^n\frac{\mathbf{s}}{||\mathbf{s}||} \]

where \(\sigma_{eff}=\sqrt{\frac{3}{2}}||\mathbf{s}||\), \(A, \sigma_0, n, Q\) are parameter, and \(R\) is the gas constant.
