Homework Statement
I am using the 3D implementation of Hooke's law as found in wikipedia at: https://en.wikipedia.org/wiki/Hooke's_law
I need to find the actual source to cite it in a master's project software write up. Many professors do not consider wikipedia to be an acceptable source, from what I've heard.
Homework Equations
\begin{equation}
\begin{bmatrix}
\sigma_{11} \\
\sigma_{22} \\
\sigma_{33} \\
\sigma_{23} \\
\sigma_{13} \\
\sigma_{12}
\end{bmatrix}
=
\begin{bmatrix}
2 \mu + \lambda & \lambda & \lambda & 0 & 0 & 0 \\
\lambda & 2 \mu + \lambda & \lambda & 0 & 0 & 0 \\
\lambda & \lambda & 2 \mu + \lambda & 0 & 0 & 0 \\
0 & 0 & 0 & \mu & 0 & 0 \\
0 & 0 & 0 & 0 & \mu & 0 \\
0 & 0 & 0 & 0 & 0 & \mu
\end{bmatrix}
\begin{bmatrix}
\varepsilon_{11} \\
\varepsilon_{22} \\
\varepsilon_{33} \\
2 \varepsilon_{23} \\
2 \varepsilon_{13} \\
2 \varepsilon_{12}

The Attempt at a Solution
I skimmed through the cited Walter Lewin MIT course lectures and did not see it.
I found the cited book "Advanced Strength and Applied Elasticity" on Google books, but it omits major pages.
I just need to know for certain where it comes from to cite it properly. I would like to avoid tracking down a copy of a hard book if possible, especially if I don't know the book has what I need.
