The Radius of Gyration of a Convex Body [PDF]

open access: yesProceedings of the American Mathematical Society, 1962
The purpose of this note is to establish an inequality of isoperimetric type for convex bodies. Let K be a bounded convex body and I a line through its centroid; let 5(K, 1) be the supremum of distances of points of K from 1, I(K, 1) the moment of inertia of K about 1, and g(K, 1) the radius of gyration [I(K, 1)/mass K]1112 of K about 1.

A parallel Discrete Element Method to model collisions between non-convex particles

open access: yesEPJ Web of Conferences, 2017
In many dry granular and suspension flow configurations, particles can be highly non-spherical. It is now well established in the literature that particle shape affects the flow dynamics or the microstructure of the particles assembly in assorted ways as
