Function youngs_modulus


\begin{boxedminipage}{\textwidth} \begin{verbatim}E = youngs_modulus(c,l)\end{verbatim} \end{boxedminipage}

Calculate Youngs modulus $E_l$ from $6\times6$ elastic constants matrix $C_{ij}$ This is the modulus for loading in the $l$ direction. Formula is from W. Brantley, Calculated elastic constants for stress problems associated with semiconductor devices. J. Appl. Phys., 44, 534 (1973).

c -- real(dp), intent(in), dimension(6,6)

l -- real(dp), dimension(3), intent(in)

Return value -- real(dp)
