Spheropolygon
WebApr 15, 2014 · A spheropolygon is defined as the Minkowski sum of a polygon with N vertices and a disk with radius r (also known as spheroradius) ( Dobrohotoff et al., 2012) (1) P ⊕ Q = { u + v u ∈ P, v ∈ Q }, where u and v are the sets of points belonging to the polygon P and disk Q, respectively. Note that ⊕ is symmetric ( i.e., P ⊕ Q ≡ Q ⊕ P ). WebJan 31, 2024 · To be considered as accurately representative of the spatial distribution of constituent’s intrinsic properties, referred to as a Representative Volume Element (RVE), a single numerical sample or SVE must usually be of considerable size, which is limited by modelling and analysis issues.

WebDec 8, 2014 · Under crowd conditions, a more accurate pedestrian shape has advantages over the traditional single or three-disks model. We developed a method for simulating pedestrian dynamics in a large dense crowd of spheropolygons adapted to the cross section of the chest and arms of a pedestrian. WebThe continuum analysis of each particle, which is represented by a spheropolygon element, is performed using the BEM method. This computational framework allows an instant calculation of the stress field and therefore provides important insights into the roles of sub-particle stress in particle breakage. It is an effective tool for reproducing ...
