Q$\mathrm{.}5$: Second order tensors stress $()$ and strain $(lon)$ are related as $,$ where $C$ is a

fourth order tensor defining material properties. Determine the tensor $C^{\text{'}}$ relating the

deviatoric stress ${}^{\text{'}}$ and deviatoric strain $lo{n}^{\text{'}}$ as ${}_{ij}^{\text{'}}=C_{\text{j}\text{j}\text{k}\text{i}}^{\text{'}}lo{n}_{ke}^{\text{'}}.$
