Question 2 The 3D strain tensor at a particular point Q in a material is given by the following matrix: \begin{equation*} \epsilon_{ij} = \begin{bmatrix} 1 & 3 & -2 \\ 3 & 1 & -2 \\ -2 & -2 & 6 \end{bmatrix} \times 10^{-4} \end{equation*} The strains within the above matrix have been multiplied by $10^4$ to make computation easier (hence the $10^4$ outside). Use the values in the matrix for computations, but add the correct multiplier in your answers. (a) Decompose the strain tensor above into a hydrostatic and deviatoric strain tensor. [Leave the $10^4$ outside each matrix as above] [7] (b) The principal strains for this system are integer values (when multiplied by $10^4$). One of the principal strains (the minimum principal strain $\epsilon_3$) is exactly -2 ($\times 10^4$). Establish the principal strain cubic equation using the integer values in the above matrix and determine the other two principal strains $\epsilon_1$ and $\epsilon_2$ as well as the absolute value of maximum shear strain at point Q. Give the maximum shear strain answer according to both engineering and tensor definitions of shear strain. Convert your answers to microstrain (i.e. $\times 10^{-6}$ rather than $\times 10^{-4}$) [16] (c) Determine the three direction cosines ($l_3$, $m_3$, $n_3$) of the minimum principal strain direction with respect to the original x,y,z coordinate axes. (i.e. direction cosines for the $\epsilon_3$ direction). $\epsilon_3$ is given in Part (b). [7] Continued overleaf Page 2 of 6

They decided to go to one of the best restaurants in town, called 'Proper Pizza'. Andre ate a pizza with arugula. After eating, nearly 30 minutes later, he became sick. His friends took him to the hospital. Andre had food poisoning. Since then, Andre never ate pizza again. Furthermore, everything that reminds him of pizza, he starts to feel sick or have some symptoms of nausea.
