DEM Implementation for Elliptical and Soft Particles Civil 481 -Semester Project Report

2025

Abstract

This report details the development and implementation of a Discrete Element Method (DEM) simulation designed to model the behavior of deformable two dimensional (2D) elliptical particles. The simulation implements particle-particle and particle-wall interactions, with the foundational contact model based on Hertzian theory, extended with modifications to account for geometric nonlinearities. A central focus of this project is on the deformation of elliptical particles under various loading conditions and the subsequent evolution of the deformations post-collision.

Project

A project is any undertaking, carried out individually or collaboratively and possibly involving research or design, that is carefully planned to achieve a particular goal. An alternative view sees a project managerially as a sequence of events: a "set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations". A project may be a temporary (rather than a permanent) social system (work system), possibly staffed by teams (within or across organizations) to accomplish particular tasks under time constraints.

Deformation (physics)

In physics and continuum mechanics, deformation is the transformation of a body from a reference configuration to a current configuration. A configuration is a set containing the positions of all particles of the body. A deformation can occur because of external loads, intrinsic activity (e.g. muscle contraction), body forces (such as gravity or electromagnetic forces), or changes in temperature, moisture content, or chemical reactions, etc. Strain is related to deformation in terms of relative displacement of particles in the body that excludes rigid-body motions.

Deformation (mathematics)

In mathematics, deformation theory is the study of infinitesimal conditions associated with varying a solution P of a problem to slightly different solutions Pε, where ε is a small number, or a vector of small quantities. The infinitesimal conditions are the result of applying the approach of differential calculus to solving a problem with constraints. The name is an analogy to non-rigid structures that deform slightly to accommodate external forces.
