11.3.8 Shear Retention Factor `USRBET`

Subroutine USRBET determines the shear retention factor $\beta$ in Total Strain crack models [§6.2], depending on ambient variables (temperature, concentration, maturity) and time.

(Fortran)

      SUBROUTINE USRBET( usrkey, te, co, ma, ti, beta )

$\begin{figure}\centering \begin{tabbing} out~~\=\textsc{dbl}~~\=\texttt{abcdef... ...bl}\>\texttt{beta}\>Shear retention factor. \\ [-3ex] \end{tabbing} \end{figure}$

usrkey: is the user-supplied keyword from input table 'MATERI'. This can be used to model various functions within one subroutine.
beta: is the shear retention factor $\beta$ calculated from the input arguments.
