Discrete Element Method Modeling for the Failure Analysis of Dry Mono-Size Coke Aggregates

An in-depth study of the failure granular materials, which is known as a mechanism to generate defects, can reveal facts regarding origin imperfections, such cracks in carbon anodes. The initiation and propagation anode, especially horizontal below stub-holes, reduce anode efficiency during electrolysis process. analysis coke aggregates be employed determine appropriate recipe operating conditions order avoid formation In this paper, it will shown that particular mode responsible for crack generation second-order work criterion analyze aggregate specimens relationships between work, kinetic energy, instability material are investigated. addition, modeled by exploiting discrete element method (DEM) micro-mechanical behavior dry compaction optimal number particles required DEM simulations determined. effects confining pressure strain rate two important process parameters on studied. results increasing enhances probability diffusing specimen. On other hand, increase augments chance localization
