Description

The geometric strain, \(\epsilon_{ij}\) is the symmetric derivative of the Displacement field, \(u\). It depends only on the field, and not on any material properties. Specifically,

\[
    \epsilon_{ij} = \frac12\left({\frac{\partial u_i}{\partial x_j}} + 
                    {\frac{\partial u_j}{\partial x_i}}\right)
     \] (6.142)
