11.3.5 Tensile Strength `USRTST`

Subroutine USRTST determines the tensile strength f_t in Total Strain crack models [§6.2], depending on ambient variables (temperature, concentration, maturity) and time.

(Fortran)

      SUBROUTINE USRTST( usrkey, te, co, ma, ti, ft )

$\begin{figure}\centering \begin{tabbing} out~~\=\textsc{dbl}~~\=\texttt{abcdef... ...textsc{dbl}\>\texttt{ft}\>Tensile strength. \\ [-3ex] \end{tabbing} \end{figure}$

usrkey: is the user-supplied keyword from input table 'MATERI'. This can be used to model various functions within one subroutine.
ft: is the tensile strength f_t calculated from the input arguments.
