Read MoreMar 01, 1995 The platy clay particles do possess the tendency to reorient themselves in the most stable condition against applied stress. One may conceive of developing a soil model directly relating particle orientation and applied stress. In this study an angle , which is the preferred therefore stable orientation of clay particles, is introduced.
