APPENDIX

Figure 1 Variation of the normal stress contribution of strong and weak contacts to σ11 in hard granular assemblies.

Figure 2 Variation of the normal stress contribution of strong and weak contacts to σ33 in hard granular assemblies.

Figure 3 Variation of the tangential stress contribution of strong and weak contacts to σ11 in hard granular assemblies.

Figure 4 Contribution of strong and weak contacts to principal stresses and deviator stress μ =0.1 in hard granular assemblies under shearing.

Figure 5 Contribution of strong and weak contacts to principal stresses and deviator stress μ =0.25 in hard granular assemblies under shearing.

Figure 6 Contribution of strong and weak contacts to principal stresses and deviator stress μ =0.5 in hard granular assemblies under shearing.

(b) Figure 9 Variation of measures of fabriccoordination numbers during shearing. The plots show the variations of apparent coordination number (Za) and mechanical coordination number (Zm) versus the deviator fabric of all the contacts (a) and the deviator fabric of strong contacts (b). In soft systems, the variation of Zm and Za were almost identical and hence presented as single plots for different values of μ.
