“…The compaction of the packing is achieved by particle growth. The resulting contact forces cause a subsequent rearrangement of the particles (Winkler et al 2014). The growth of the particles is controlled by a confined pressure referring to a compaction energy similar to the Proctor-test.…”

“…Therefore numerical simulations can be used to gain information about micro mechanical behaviour and to facilitate development of a micromechanics-based constitutive model of discrete materials. Unlike physical and analytical models, numerical simulations can provide essentially any desired piece of information (stresses, strain, detailed micromechanical statistics, and spatial distribution of matrix parameters) at any step during loading (Salehi Sadaghiani et al 2014;Winkler et al 2014).…”

Abstract. Tensile failure in unsaturated cohesive soils during desiccation is important for the design of geotechnical applications such as capping systems of landfills and sealing material of dikes. This study presents the results of different initial parameters of compacted clay samples such as gravimetric water content, dry density and degree of saturation. These parameters are varied systematically for each test to find the correlation between those parameters and the tensile failure. The tensile failure for all tests occurred by a comparable constant change of the degree of saturation. The soil specific saturation ratio Sr,s is defined as the quotient of saturation changes ΔSr to initial saturation Sr,0. This parameter related to the total suction shows an equal course for all results. All in all, the course of the soil specific saturation ratio Sr,s is independent of all initial parameters. These results provide a physical and hydraulicmechanical description for modelling the desiccation process. To demonstrate the initiation and progress of tensile failure, the experimental results are modelled with a Discrete Element Method (DEM) approach.
