The three graphs are titled Stress dash Strain colon three 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 five eight, zero point six six nine, zero point six seven two, and zero point six seven five. In graph b, void ratios are zero point six four seven, zero point six five zero, zero point six five three, and zero point six five eight. In graph c, void ratios are zero point six four five, zero point six five zero, zero point six five three, and zero point six five three. In all graphs, curves rise steeply to between about seventy-five and eighty kilopascals at around two to four per cent strain, then gradually decrease towards about fifty-eight to sixty five kilo pascal by fifteen per cent strain.Stress–strain curves of random 3-mm diameter sphere samples subjected to triaxial compression at drop heights of 0.305 m (a), 0.610 m (b) and 0.915 m (c)
