6.10 An element of soil with a maximum shear modulus of 700,000 psf and an undrained strength of 1000 psf is subjected to the time history of shear stress shown below. Assuming that the back- bone curve is hyperbolic, and that the soil follows the extended Masing criteria, plot the result- ing stress-strain behavior. Mark all points at which the unloading-reloading rules governing the stress-strain behavior change (i.e. mark as 1-2 at the point where control over the stress-strain response shifts from Rule 1 to Rule 2). t-pst 1000 Time -1000 Figure P6.10
