Deformation Behavior of Sands under Cyclic Loading - A Micro-Structural Approach
The overall objective of this research is to develop a constitutive model for granular materials accounting for its micro-structure. The project focussed on the theoretical development of stress-strain relationship from a micro-mechanics approach, the law governing the force-displacement behavior at a contact under a general cyclic loading condition, and the mathematical characterization of the packing structure in the form of fabric tensor of a granular assembly. Experimental tests were conducted on rod assemblies in a directional shear box to verify the developed theory. Analytical expressions were obtained for the stiffness constants of anisotropic granular assemblies. Keywords: Granular mechanics; Constitutive law; Packing structure; Soil fabric; Random packings; Soil moduli; Structural amisotropy. (JES)
