Zukoski, Charles F. Jogun, Suzanne Michelle 2015-09-25T20:44:08Z 2015-09-25T20:44:08Z 10000-01-01 1998 1998 The second type of clay particles have a smaller aspect ratio approximately equal to 8. These suspensions demonstrate shear thickening at $\phi \ge$ 0.50 and also have a shear history dependent elastic modulus, G$\sp\prime.$ In the shear thinning region G$\sp\prime$ decreases with increasing shear rate. In the shear thickening region the modulus increases rapidly. Since G$\sp\prime$ is related to particle alignment, these results imply that the particle alignment increases until thickening occurs. At that point the particles become highly misaligned. These alignment changes are confirmed by conductivity measurements. Made available in DSpace on 2015-09-25T20:44:08Z (GMT).
