+The corrected stress ($\hat{\sigma}$) and backstress ($\hat{X}$) are respectively calculated as:
+\[\hat{\sigma} = L_{ijmn}T_{mnkl}\sigma_{kl}\]
+\[\hat{X}= L_{ijmn}T_{mnkl}X_{kl}\]
+The backstress tensor is calculated using the Armstrong-Frederick model:
+\[dX = S_{x}[C_{x}d{\epsilon^p}-Xd\bar{\epsilon}^p]\]
