Analysis of Deformation and Damage Processes in Soil-Tool Interaction Problems
Jan Maciejewski , Zenon Mróz
AbstractThe processes of interaction of earth-working machines with soils are related to large inelastic deformation inducing soil structure variation with dilatancy, compaction and critical states developing during the process. The effects of hardening, softening, strain localization in shear or tensile rupture bands accompany the machine tools operation in the cohesive soil. The aim of this contribution is to provide simplified incremental analysis of some typical processes, such as soil cutting, digging, filling, and compaction among others, by applying constitutive models relevant to the type of process. The aim of analysis is to predict the deformation modes, forces interaction and energy required for the process, and also to generate optimal process control in order to minimize some parameters of soil-tool interaction.
