The paper extends the formal structure of the fabric based analysis of cohesion-less granular materials to cemented granular materials such as concrete. The stress-fabric and strain-fabric relationships are derived, and both are seen to be sensitive to particle angularity and maximum particle size. The contributions of the isotropic and anisotropic parts of the micro structural stress and strain are identified and a recently developed discrete element capability used to investigate their separate contributions to the macro behaviour in uniaxial compression. The anisotropic part of the micro-structural stress plays a dominant role in determining the peak strength. However, post peak ductility is largely controlled by the isotropic part. Remarkably fabric anisotropy, which depends strongly on particle angularity, is seen to result in higher hydrostatic pressures. This strengthens the “internal confinement mechanism” and accounts for the superior strength of specimens with angular aggregates observed in experiments.

本文将基于织物的无粘性颗粒材料分析的形式结构扩展到水泥颗粒材料（例如混凝土）。得出了应力-织物和应变-织物的关系，并且两者都被认为对颗粒的角度和最大的颗粒尺寸敏感。确定了微结构应力和应变的各向同性和各向异性部分的贡献，并使用了最近开发的离散元素功能来研究它们对单轴压缩中宏观行为的单独贡献。微结构应力的各向异性部分在确定峰值强度中起主要作用。但是，峰后延性很大程度上受各向同性部分控制。织物各向异性非常明显，这很大程度上取决于粒子的角度，可以看到会导致更高的静水压力。这加强了“内部约束机制”，并说明了在实验中观察到的具有角向聚集体的试样具有较高的强度。
