Topology, Structure and Functionality: Analysis, Modelling and Experimentation of Dense Granular Deformation in 2D and 3D

Abstract

A three-pronged approach is employed to study mesoscale phenomens in dense granular materials. This approach interrelates the key elements of topology, structure and function to uncover principles of self-organization in dense granular materials. For the first time, we fuse Structural Mechanics techniques, Graph Theory, and nascent mathematical and statistical techniques from Complex Networks and Dynamical Systems to characterize the stability and dynamics of deforming granular materials. We summarise here five distinct projects undertaken by our group in fulfillment of the objectives of this program. Each project focuses on a particular class of data, distinguished by one or several of the following factors: (i) the type of material studied (photoelastic, and natural geomaterials including Hostun sand, Masonry-concrete and silica-concrete sand, partially molten metal-silicate rock (Kernouve)) (ii) the loading condition, and (iii) source of data, i.e. simulation versus experiment.
