The three graphs are titled Stress dash Strain colon six-millimetre Spherical Particles at zero point three zero five-metre, zero point six one zero-metre, and zero point nine one five-metre drop heights, labelled a, b, and c. The horizontal axis is Strain in per cent from zero to fifteen. The vertical axis is Deviatoric Stress in kilopascal from zero to ninety. Each graph includes four curves for zero Sieve, one Sieve, two Sieves, and three Sieves, with void ratios listed in the legends. In graph a, void ratios are zero point six eight one, zero point six eight three, zero point six eight six, and zero point six eight six. In graph b, void ratios are zero point six seven two, zero point six seven five, zero point six seven eight, and zero point six eight one. In graph c, void ratios are zero point six six one, zero point six six seven, zero point six six nine, and zero point six seven two. In all graphs, curves rise steeply to between about seventy to eighty-five kilopascals at around two to five per cent strain and decrease gradually towards about fifty-five to sixty-five kilopascals at fifteen per cent strain.Stress–strain curves of random 6-mm diameter sphere samples subjected to triaxial compression at drop height of 0.305 m (a), 0.610 m (b) and 0.915 m (c)
