11.1.1 Young's Modulus USRYOU

If USRYOU is specified in table 'MATERI' then subroutine USRYOU must be supplied to set up Young's modulus E for elastic or viscoelastic material. This subroutine is particularly used to specify ambient influence (temperature, concentration, maturity) and time dependency.

    (Fortran)


      SUBROUTINE USRYOU( usrkey, te, co, ma, ti, young )
\begin{figure}\centering
\begin{tabbing}
out~~\=\textsc{dbl}~~\=\texttt{abcdef...
...xtsc{dbl}\>\texttt{young}\>Young's modulus. \\ [-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.

young
is the stiffness calculated from the input arguments.
