)

Computation of the element stiffness elasticity matrix for $P_1$-Lagrange method. The method for numbering the degrees of freedom is local block numbering.

The elasticity matrix obtained from Hooke's law is given by

\[C=\left\{\begin{array}[ccc] &\lambda+2\mu &\lambda &0\\ &\lambda &\lambda+2\mu &0\\ &0 &0 &\mu \end{array} \right.\]
