Two soil samples were compressed to $150$kPa, then triaxially sheared to failure following CD stress path. One is saturated sample $($sample #$1,$ suction $=0)$ and the other is unsaturated sample $($sample #$2,$ suction $=50$ kPa$).$ The following information has known from laboratory tests: Yield stress $=150($kPa$)$ Elastoplastic compression index $=0\mathrm{.}12$ Elastic compression index $=0\mathrm{.}01$ Poisson$$s ratio $=0\mathrm{.}3,$ parameter $=0\mathrm{.}007($kPa$-1)$; parameter $=0\mathrm{.}35$ Friction angle $=28($degree$),=17($degree$)$ Initial void ratio $=1\mathrm{.}25,$ Initial mean stress $=150($kPa$),$ Initial deviator stress $=0$ Please calculate the stress$-$strain curve $($deviator stress versus deviator strain$)$ and shear$-$volume change curve $($volumetric strain and deviator strain$)$ for above two samples when subjected to the triaxial CD stress path. $(1)$ Plot the stress$-$strain curve $($deviator stress versus deviator strain$)$ for sample #$1,(2)$ Plot the shear$-$volume change curve $($volumetric strain and deviator strain$)$ for sample #$1,(3)$ Plot the stress$-$strain curve $($deviator stress versus deviator strain$)$ for sample #$2,$ and $(4)$ Plot the shear$-$volume change curve $($volumetric strain and deviator strain$)$ for sample #$2.*$Note: please use excel for calculation and plotting.
