Figure 26
The six scatter plots are arranged in three rows and two columns. The left column is titled Experiment versus Numerical Model for six-millimetre Spherical Particles at zero point three zero five-metre, zero point six one zero-metre, and zero point nine one five-metre heights. The horizontal axis is the number of Sieves from zero to three. The vertical axis is Void Ratio, e, from zero point five zero to zero point eight five. Each plot includes points for Experiment, P F C Radius Expansion, and P F C Air Pluviation. Experimental values range approximately from zero point six six to zero point six eight. P F C Radius Expansion values range approximately from zero point seven six to zero point seven nine. P F C Air Pluviation values range approximately from zero point six zero to zero point six three. The right column is titled Percentage Error for the same heights. The horizontal axis is the number of Sieves from zero to three. The vertical axis is the error in per cent from zero to twenty. P F C Radius Expansion errors range approximately from fourteen to seventeen per cent. P F C Air Pluviation errors range approximately from four to eleven per cent.Comparison of void ratio (a) and the percentage error (b) of experimental samples and numerical samples
