ADEM simulation for the analysis of breakage behavior of powder compact

Research output: Contribution to journalArticle

Abstract

A new simulation approach using Advanced Distinct Element Method (ADEM) was proposed to predict the compression behavior and the characteristic of the compact. Relationship between compression load and compressive strength of compact have been analyzed. The breakage behavior and discrete motion of particles during compression was simulated by ADEM. ADEM parameters represent the property of samples, it was determined to fit the experimental results of load-displacement curve obtained by single particle compression test. Internal structure of compact was measured by X-ray CT imaging, information of particle breakage and density distribution was obtained. High density compact could make as a result of high compression load, on the other hand, compressive strength of compact decrease when the compression load was much high. There was optimum condition to obtain the tough compact. Simulation analysis could visualize the compression behavior of compact, fine powder ratio suggest the optimum compression load for powder compact.
