This book was released on 2019-11-06 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Glass and laminated glass are widely used for structural members in industry. To investigate how they fracture under impact as well as the subsequent fragmentation, the combined finite-discrete element method (FEM/DEM) was employed in this thesis. The mode I fracture model was extended for glass by changing the strain softening curve to a bilinear-like exponential decay shape. Analysis based on this model was performed and numerical examples in both 2D and 3D were investigated. Parametric study was carried out and conclusion was reached that the tensile strength, fracture energy and thickness are the top three parameters in improving the performance of monolithic glass under impact. Two mixed mode I + II fracture models (the elasto-plastic fracture model and the scaling model) were developed for the glass and the interface in laminated glass. The elasto-plastic model reached some similarity with the Mode I model, while some modification is needed for the scaling model. Results on laminated glass from the FEM/DEM were compared and verified with that from FEM, DEM and experiments. Parametric study on the laminated glass was performed, showing better capacity in energy absorption over monolithic glass.
Book Synopsis The Combined Finite-Discrete Element Method by : Antonio A. Munjiza
Download or read book The Combined Finite-Discrete Element Method written by Antonio A. Munjiza and published by John Wiley & Sons. This book was released on 2004-04-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Extended Finite Element Method by : Soheil Mohammadi
Download or read book Extended Finite Element Method written by Soheil Mohammadi and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important textbook provides an introduction to the concepts of the newly developed extended finite element method (XFEM) for fracture analysis of structures, as well as for other related engineering applications. One of the main advantages of the method is that it avoids any need for remeshing or geometric crack modelling in numerical simulation, while generating discontinuous fields along a crack and around its tip. The second major advantage of the method is that by a small increase in number of degrees of freedom, far more accurate solutions can be obtained. The method has recently been extended to nonlinear materials and other disciplines such as modelling contact and interface, simulation of inclusions and holes, moving and changing phase problems, and even to multiscale analyses. The book is self contained, with summaries of both classical and modern computational techniques. The main chapters include a comprehensive range of numerical examples describing various features of XFEM.

Book Synopsis 3D Discrete Element Workbench for Highly Dynamic Thermo-mechanical Analysis by : Damien Andre
Download or read book 3D Discrete Element Workbench for Highly Dynamic Thermo-mechanical Analysis written by Damien Andre and published by John Wiley & Sons. This book was released on 2015-10-26 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. 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.

Download or read book The Cell Method written by Elena Ferretti and published by Momentum Press. This book was released on 2014-02-02 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cell Method (CM) is a computational tool that maintains critical multidimensional attributes of physical phenomena in analysis. This information is neglected in the differential formulations of the classical approaches of finite element, boundary element, finite volume, and finite difference analysis, often leading to numerical instabilities and spurious results. This book highlights the central theoretical concepts of the CM that preserve a more accurate and precise representation of the geometric and topological features of variables for practical problem solving. Important applications occur in fields such as electromagnetics, electrodynamics, solid mechanics and fluids. CM addresses non-locality in continuum mechanics, an especially important circumstance in modeling heterogeneous materials. Professional engineers and scientists, as well as graduate students, are offered: • A general overview of physics and its mathematical descriptions; • Guidance on how to build direct, discrete formulations; • Coverage of the governing equations of the CM, including nonlocality; • Explanations of the use of Tonti diagrams; and • References for further reading.
