Book Description
Thermodynamically consistent space-time discretization of non-isothermal mechanical systems in the framework of GENERIC
Author: Schiebl, Mark GeorgPublisher: KIT Scientific Publishing
ISBN: 3731511177
Category : Technology & Engineering
Languages : en
Pages : 238
Book Description
The present work addresses the design of structure-preserving numerical methods that emanate from the general equation for non-equilibrium reversible-irreversible coupling (GENERIC) formalism. Novel energy-momentum (EM) consistent time-stepping schemes in the realm of molecular dynamics are proposed. Moreover, the GENERIC-based structure-preserving numerical methods are extended to the context of large-strain thermoelasticity and thermo-viscoelasticity.
Multi-field modeling and simulation of fiber-reinforced polymers
Author: Schulte, JonathanPublisher: KIT Scientific Publishing
ISBN: 3731512513
Category : Technology & Engineering
Languages : en
Pages : 176
Book Description
This work proposes a new numerical approach for analyzing the behavior of fiber-reinforced materials, which have gained popularity in various applications. The approach combines theories and methods to model the fracture behavior of the polymeric matrix and the embedded fibers separately, and includes a modified plasticity model that considers the temperature-dependent growth of voids. Tests are conducted to explore different types and sequences of failure in long fiber-reinforced polymers.
EAS Elements for Solid Mechanics - Mesh Distortion Insensitive and Hourglassing-Free Formulations with Increased Robustness
Author: Pfefferkorn, RobinPublisher: KIT Scientific Publishing
ISBN: 3731512718
Category : Science
Languages : en
Pages : 218
Book Description
Proposed in the early 1990s, the enhanced assumed strain (EAS) method is one of the probably most successful mixed finite element methods for solid mechanics. This cumulative dissertation gives a comprehensive overview of previous publications on that method and covers recent improvements for EAS elements. In particular, we describe three key issues of standard EAS elements and develop corresponding solutions.
Inverse dynamics of underactuated flexible mechanical systems governed by quasi-linear hyperbolic partial differential equations
Author: Ströhle, TimoPublisher: KIT Scientific Publishing
ISBN: 3731513366
Category :
Languages : en
Pages : 174
Book Description
This work is about the inverse dynamics of underactuated flexible mechanical systems governed by quasi-linear hyperbolic partial differential equations subjected to time-varying Dirichlet boundary conditions that are enforced by unknown, spatially disjunct, hence non-collocated Neumann boundary conditions.
Characterisation and modelling of PC/ABS blends
Author: Hund, JonasPublisher: KIT Scientific Publishing
ISBN: 3731511576
Category : Technology & Engineering
Languages : en
Pages : 238
Book Description
The present work deals with the characterisation and multi-scale modelling of the large-strain response of ternary polymer blends. In a homogenised constitutive modelling approach, particularly the deformation behaviour featuring plastic dilatancy is investigated. Concerning the micromechanical modelling, constitutive models are proposed for the blends' individual phases and compared regarding their capabilities to capture the composition-dependent fracture toughness in unit cell models.

A Simple Introduction to the Mixed Finite Element Method
Author: Gabriel N. GaticaPublisher: Springer Science & Business Media
ISBN: 3319036955
Category : Mathematics
Languages : en
Pages : 142
Book Description
The main purpose of this book is to provide a simple and accessible introduction to the mixed finite element method as a fundamental tool to numerically solve a wide class of boundary value problems arising in physics and engineering sciences. The book is based on material that was taught in corresponding undergraduate and graduate courses at the Universidad de Concepcion, Concepcion, Chile, during the last 7 years. As compared with several other classical books in the subject, the main features of the present one have to do, on one hand, with an attempt of presenting and explaining most of the details in the proofs and in the different applications. In particular several results and aspects of the corresponding analysis that are usually available only in papers or proceedings are included here.
