{title2=$\overline{\boldsymbol\varepsilon}=\sum_gv_gR_g\boldsymbol\varepsilon^{(g)}R_g^T$}

An ideal orientation average $\overline{\boldsymbol\varepsilon}=\sum_g v_gR_g\boldsymbol\varepsilon^{(g)}R_g^T$. Random orientation averages a traceless single-grain growth tensor to zero, while <crystallographic texture> can retain a directional bulk <strain>. <crystal grain> constraints can modify this simple independent-grain estimate.
