Unformatted text preview: A to B is isotropic normal compression, with increasing cell pressure, drainage taps open and no deviator (shear) stress applied. It is first loading, so changes in specific volume are mainly plastic (irrecoverable) B to C is isotropic unloading (reduction in cell pressure with the drainage taps open and no shear). The elastic component of volumetric compression that occurred during loading over the same stress range is recovered....
