【摘要】 本文通过引入微观组构张量和接触密度分布函数,将散粒体的微观力学变量与宏观力学变量联系起来,从而建立了散粒体的本构理论。其中包括二维和三维组构各向异性随机排列散粒体应力应变关系。同时,对组构张量与刚度张量之间的对应关系作了全面讨论,并深入分析了微观组构量与散粒体宏观弹性模量之间的相互关系。更多还原

【Abstract】 The relationship between fabric tensor and contact density distribution functions, and the relationship between fabric tensor and stress tensor are analyzed. The constitutive relations of granular materials are derived, including two-dimension random packing and three-dimension random packing The corresponding relations between fabric tensor and stiffness tensor are discussed. Relationships between fabric tensor and the moduli of assemblies are given.更多还原
