Abstract
<p>The binary granular mixture consisting of two types of particles, large particles and small particles, are divided into three types of properties: small particle skeleton structure, intermediate skeleton structure, and large particle skeleton structure. The properties of the intermediate skeleton structure vary with the large particle content, so it is important to understand the micromechanical state of the intermediate skeleton structure. In this study, DEM was used to reproduce the angle of reposed experiment conducted on binary granular mixtures, and the visualized strong contact vectors, contact forces for each contact type, and distances between the centers of gravity of the large particles were analyzed. The results show that the strong contact vectors visualized started to appear from the large particle content where the intermediate skeleton structure begins, and developed toward the top of the mountain as the number of large particles increases. The contact forces between large particles and large particles, between large particles and small particles increased in the intermediate skeleton structure, while the contact forces between small particles and small particles decreased. The distance between the centers of gravity of large particles was shorter in the vertical direction than in the horizontal direction.</p>
