1. Using the blank graphs included below graph the deviatoric stress (q) mean effective stress ( \( p \) '), void ratio (e), and strain ( \( \varepsilon \) ) for a soil with the following properties and then answer questions a) through f). - initial yield surface size ( \( \mathrm{p}^{\prime} \mathrm{c} \) ) \( =30 \mathrm{kPa} \) - Overconsolidation ratio \( (O C R)=1.5 \) assume isotropic consolidation and mechanical unloading - Drainage permitted during shearing a) What is the initial void ratio prior to shearing? b) What is the mean effective stress at failure? c) What is the size of the yield surface ( p 'c) at failure? d) What is the void ratio at failure? e) Does the sample dilate during shear? If so how much (submit your answer in terms of change in void ratio \( (\Delta \mathrm{e}) \) )? f) At what deviatoric stress does the sample transition from elastic behavior to elastoplastic behavior?
