11.3.9 Compressive Strength USRCST


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

    (Fortran)


      SUBROUTINE USRCST( usrkey, te, co, ma, ti, fc )
\begin{figure}\centering
\begin{tabbing}
out~~\=\textsc{dbl}~~\=\texttt{abcdef...
...sc{dbl}\>\texttt{fc}\>Compressive 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.

fc
is the compressive strength fc calculated from the input arguments.
