11.3.7 Mode-I Tensile Fracture Energy `USRGF1`

Subroutine USRGF1 determines the tensile fracture energy G_f^I in Smeared Cracking [§6.1] or Total Strain crack models [§6.2], depending on ambient variables (temperature, concentration, maturity) and time.

(Fortran)

      SUBROUTINE USRGF1( usrkey, te, co, ma, ti, gf1 )

$\begin{figure}\centering \begin{tabbing} out~~\=\textsc{dbl}~~\=\texttt{abcdef... ...exttt{gf1}\>Mode-I tensile fracture energy. \\ [-3ex] \end{tabbing} \end{figure}$

usrkey: is the user-supplied keyword from input table 'MATERI'. This can be used to model various functions within one subroutine.
gf1: is the Mode-I tensile fracture energy G_f^I calculated from the input arguments.
