- Objectives
- ----------
- This is the second international conference on DEM to be held in
- the U.S.A. Its purpose is to bring engineers, scientists,
- mathematicians, and computer scientists active in this developing
- field together to present their work, discuss relevant issues and
- document the current state of DEM technology. Technical papers are
- sought in either the theoretical development or application of DEM.
- Typical areas of interest are summarized below:
-
- * Computational models for physical simulation
- * Analysis of dynamic contact/impact problems
- * Animation/visualization of multi-body simulations
- * Contact detection and contact force algorithms
- * Discrete particle modeling of granular and fluid flow systems
- * Cellular automata and lattice gas modeling
- * Molecular dynamics modeling
- * Particle system modeling
- * Advanced computational DEM algorithms, including the use of
- supercomputing and parallel computing environments, and object
- oriented programming techniques.
-
- Contributions are not restricted solely to the topics described
- above, but are also encouraged from researchers working in related
- research and development areas.
-
- Please note: As a large reponse is expected for the Computer
- ************ Graphics & Physical Simulation section, there may be
- cause to limit the number of speakers. Therefore we
- advise those of you interested to submit abstracts as
- soon as possible.
-
- Papers for presentation will be selected on the review of a
- technical abstract of approximately 500 words. Please mail or email
- an abstract by October 7th, 1992 to the following address:

- Background
- ----------
- Continuum models of materials have dominated our approach to the
- analysis of material behavior. Recently a number of numerical methods
- which start at the microscopic level have gained attention, including,
- discrete element, cellular automata, lattice gas, molecular dynamics
- and percolation models. These theories, here referred to as discrete
- element methods, offer a different view of the physics of material
- behavior to the traditional techniques, such as finite element.
-
- Some have proposed that our thinking about material behavior has
- been too greatly influenced by continuum theories, which are derived
- without reference to the "ball-bearing" like atomic world which we
- know exists at a finer level of detail. The continuum description has
- proved quite accurate but is incomplete because we have no means of
- calculating the physical constants, such as viscosity, which are
- determined by the interaction of discrete particles at the
- microscopic level. To investigate these phenomena we are forced to
- relinquish our continuum models and seek models which capture the
- discrete structure of the microworld.
-
- The simplest discrete systems, so called cellular automata, have
- been successful in simulating some aspects of the behavior of complex
- physical systems, such as gases and fluids. It has been shown that the
- macroscopic equations of dynamics arise naturally from statistical
- mechanical consideration of these systems. Recently, percolation
- models and lattice gas models have been used to investigate material
- behavior.
-
- Discrete element models, in which the particles themselves have
- internal structure and specific geometry, form a bridge between the
- micro and macro world. Geometric structure is captured by the
- potential fields of molecular dynamics or by more complex elements
- which can simulate continuum stress and deformation states, much like
- finite elements.
-
- Recently the speed of modern computers (including parallel
- architectures) and the availability of efficient algorithms have made
- large scale calculations using these discrete models particularly
- attractive.
-
-
- Examples of particular applied mechanics problems which have been
- investigated with DEM include: failure analysis of materials
- (ceramics, rocks, ice, etc), mechanical behavior of granular media,
- mechanical modeling of fractured and jointed rock masses, fluid and
- granular material flow, models of percolation paths and fracture
- networks and the development of macroscopic constitutive laws from
- microscopic discrete models.
-

- modeling of discrete systems, discontinuum analysis, or in the
- micromechanics of material behavior, should attend this conference.
