The Combined Finite-Discrete Element Method by Antonio A. Munjiza Pdf

The combined finite discrete element method is a relatively new computational tool aimed at problems involving static and / or dynamic behaviour of systems involving a large number of solid deformable bodies. Such problems include fragmentation using explosives (e.g rock blasting), impacts, demolition (collapsing buildings), blast loads, digging and loading processes, and powder technology. The combined finite-discrete element method - a natural extension of both discrete and finite element methods - allows researchers to model problems involving the deformability of either one solid body, a large number of bodies, or a solid body which fragments (e.g. in rock blasting applications a more or less intact rock mass is transformed into a pile of solid rock fragments of different sizes, which interact with each other). The topic is gaining in importance, and is at the forefront of some of the current efforts in computational modeling of the failure of solids. * Accompanying source codes plus input and output files available on the Internet * Important applications such as mining engineering, rock blasting and petroleum engineering * Includes practical examples of applications areas Essential reading for postgraduates, researchers and software engineers working in mechanical engineering.

Proceedings of the 7th International Conference on Discrete Element Methods by Xikui Li,Yuntian Feng,Graham Mustoe Pdf

This book presents the latest advances in Discrete Element Methods (DEM) and technology. It is the proceeding of 7th International Conference on DEM which was held at Dalian University of Technology on August 1 - 4, 2016. The subject of this book are the DEM and related computational techniques such as DDA, FEM/DEM, molecular dynamics, SPH, Meshless methods, etc., which are the main computational methods for modeling discontinua. In comparison to continua which have been already studied for a long time, the research of discontinua is relatively new, but increases dramatically in recent years and has already become an important field. This book will benefit researchers and scientists from the academic fields of physics, engineering and applied mathematics, as well as from industry and national laboratories who are interested in the DEM.

Computational Mechanics of Discontinua by Antonio A. Munjiza,Earl E. Knight,Esteban Rougier Pdf

Mechanics of Discontinua is the first book to comprehensively tackle both the theory ofthis rapidly developing topic and the applications that span a broad field of scientific and engineering disciplines, from traditional engineering to physics of particulates, nano-technology and micro-flows. Authored by a leading researcher who has been at the cutting edge of discontinua simulation developments over the last 15 years, the book is organized into four parts: introductory knowledge, solvers, methods and applications. In the first chapter a short revision of Continuum Mechanics together with tensorial calculus is introduced. Also, a short introduction to the finite element method is given. The second part of the book introduces key aspects of the subject. These include a diverse field of applications, together with fundamental theoretical and algorithmic aspects common to all methods of Mechanics of Discontinua. The third part of the book proceeds with the most important computational and simulation methods including Discrete Element Methods, the Combined Finite-Discrete Element Method, Molecular Dynamics Methods, Fracture and Fragmentation solvers and Fluid Coupling. After these the reader is introduced to applications stretching from traditional engineering and industry (such as mining, oil industry, powders) to nanotechnology, medical and science.

Impact Fracture of Glass. The Combined Finite-Discrete Element Study by Xudong Chen Pdf

Scientific Study from the year 2019 in the subject Engineering - Civil Engineering, Suzhou University of Science and Technology, language: English, abstract: This book introduces theoretical and practical aspects for modelling the impact fracture of glass and laminated glass using the combined finite-discrete element method (FDEM). The FDEM is a branch of the discrete element method (DEM), and combines finite element formulation into individual discrete elements. Thus, contact forces are evaluated more accurately. Regarding the fracture of glass, a Mode I-based smeared crack model is extended and employed in the FDEM, enabling crack initiation and propagation be captured naturally. Based on the employed method and the crack model, numerical examples on fracture of glass under both hard and soft impacts are presented and validated with data from computational and experimental sources. The combined finite-discrete element method is proven to be a reliable and robust tool for examining the impact fracture responses of glass.

Discrete Element Method to Model 3D Continuous Materials by Mohamed Jebahi,Damien Andre,Inigo Terreros,Ivan Iordanoff Pdf

Complex behavior models (plasticity, cracks, visco elascticity) face some theoretical difficulties for the determination of the behavior law at the continuous scale. When homogenization fails to give the right behavior law, a solution is to simulate the material at a meso scale in order to simulate directly a set of discrete properties that are responsible of the macroscopic behavior. The discrete element model has been developed for granular material. The proposed set shows how this method is capable to solve the problem of complex behavior that are linked to discrete meso scale effects.

3D Discrete Element Workbench for Highly Dynamic Thermo-mechanical Analysis by Damien Andre,Jean-Luc Charles,Ivan Iordanoff Pdf

When homogenization fails to give the right behavior law, a solution is to simulate the material at a meso scale in order to simulate directly a set of discrete properties that are responsible of the macroscopic behavior. The discrete element model has been developed for granular material. The proposed set shows how this method is capable to solve the problem of complex behavior that are linked to discrete meso scale effects. The first book solves the local problem, the second one presents a coupling approach to link the structural effects to the local ones, this third book presents the software workbench that includes all the theoretical developments.
