Book Synopsis Constitutive modelling of an additively manufactured alloy for fatigue lifing in high temperature applications by : Thomas Lindström
Download or read book Constitutive modelling of an additively manufactured alloy for fatigue lifing in high temperature applications written by Thomas Lindström and published by Linköping University Electronic Press. This book was released on 2020-04-28 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of the work presented in this Licentiate thesis is to investigate and model the cyclic behaviour of an additively manufactured ductile nickel-based superalloy, with special emphasis on modelling the stabilised material behaviour, which is of interest for fatigue life predictions. Cyclic fatigue tests at different temperatures have been performed to investigate the cyclic mechanical behaviour of the material, where specimens built in different orientations have been used to also study the anisotropic behaviour of the material. Based on the tests, a constitutive description has progressively been developed and implemented in a finite element context that incorporates the anisotropic behaviour under both elastic and inelastic deformations. In addition, the room temperature crack initiation behaviour has been studied and modelled. This thesis is divided into two parts. The first part gives an introduction and background to the research, while the second part consists of three included papers. Det huvudsakliga målet med arbetet som presenteras i denna avhandling har varit att studera och modellera det cykliska beteendet hos en additivt tillverkad duktil nickelbaserad superlegering, med fokus på att modellera det stabiliserade materialbeteendet, vilket är av intresse vid livslängdprediktering. Cykliska utmattningsprov vid olika temperaturer har utförts för att studera det cykliska beteendet hos materialet, där provstavar byggda i olika riktningar har använts för att studera materialets anisotropi. Baserat på proven har en konstitutiv beskrivning av material progressivt utvecklats och implementerats i ett finita element-verktyg, där modellen tar hänsyn till det anisotropa materialbeteendet för både elastiska och plastiska deformationer. En modell för prediktering av sprickinitiering vid rumstemperatur har också tagits fram. Denna avhandling består av två delar. Den första delen ger en introduktion samt bakgrund till forskningen, medan den andra delen består av tre inkluderade artiklar.

Book Synopsis Introduction to Unified Mechanics Theory with Applications by : Cemal Basaran
Download or read book Introduction to Unified Mechanics Theory with Applications written by Cemal Basaran and published by Springer Nature. This book was released on 2021-02-02 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text describes the mathematical formulation and proof of the unified mechanics theory (UMT) which is based on the unification of Newton’s laws and the laws of thermodynamics. It also presents formulations and experimental verifications of the theory for thermal, mechanical, electrical, corrosion, chemical and fatigue loads, and it discusses why the original universal laws of motion proposed by Isaac Newton in 1687 are incomplete. The author provides concrete examples, such as how Newton’s second law, F = ma, gives the initial acceleration of a soccer ball kicked by a player, but does not tell us how and when the ball would come to a stop. Over the course of Introduction to Unified Mechanics Theory, Dr. Basaran illustrates that Newtonian mechanics does not account for the thermodynamic changes happening in a system over its usable lifetime. And in this context, this book explains how to design a system to perform its intended functions safely over its usable life time and predicts the expected lifetime of the system without using empirical models, a process currently done using Newtonian mechanics and empirical degradation/failure/fatigue models which are curve-fit to test data. Written as a textbook suitable for upper-level undergraduate mechanics courses, as well as first year graduate level courses, this book is the result of over 25 years of scientific activity with the contribution of dozens of scientists from around the world including USA, Russia, Ukraine, Belarus, Spain, China, India and U.K.

Book Synopsis Fatigue of Structures and Materials by : J. Schijve
Download or read book Fatigue of Structures and Materials written by J. Schijve and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue of structures and materials covers a wide scope of different topics. The purpose of the present book is to explain these topics, to indicate how they can be analyzed, and how this can contribute to the designing of fatigue resistant structures and to prevent structural fatigue problems in service. Chapter 1 gives a general survey of the topic with brief comments on the signi?cance of the aspects involved. This serves as a kind of a program for the following chapters. The central issues in this book are predictions of fatigue properties and designing against fatigue. These objectives cannot be realized without a physical and mechanical understanding of all relevant conditions. In Chapter 2 the book starts with basic concepts of what happens in the material of a structure under cyclic loads. It illustrates the large number of variables which can affect fatigue properties and it provides the essential background knowledge for subsequent chapters. Different subjects are presented in the following main parts: • Basic chapters on fatigue properties and predictions (Chapters 2–8) • Load spectra and fatigue under variable-amplitude loading (Chapters 9–11) • Fatigue tests and scatter (Chapters 12 and 13) • Special fatigue conditions (Chapters 14–17) • Fatigue of joints and structures (Chapters 18–20) • Fiber-metal laminates (Chapter 21) Each chapter presents a discussion of a speci?c subject.

Book Synopsis Additive Manufacturing Volume 2 by : Prashanth Konda Gokuldoss
Download or read book Additive Manufacturing Volume 2 written by Prashanth Konda Gokuldoss and published by MDPI. This book was released on 2020-04-15 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing (AM) is one of the manufacturing processes that warrants the attention of industrialists, researchers and scientists, because of its ability to produce materials with a complex shape without theoretical restrictions and with added functionalities. There are several advantages to employing additive manufacturing as the primary additive manufacturing process. However, there exist several challenges that need to be addressed systematically. A couple such issues are alloy design and process development. Traditionally alloys designed for conventional cast/powder metallurgical processes were fabricated using advanced AM processes. This is the wrong approach considering that the alloys should be coined based on the process characteristics and meta-stable nature of the process. Hence, we must focus on alloy design and development for AM that suits the AM processes. The AM processes, however, improve almost every day, either in terms of processing capabilities or processing conditions. Hence, the processing part warrants a section that is devoted to these advancements and innovations. Accordingly, the present Special Issue (book) focuses on two aspects of alloy development and process innovations. Here, 45 articles are presented covering different AM processes including selective laser melting, electron beam melting, laser cladding, direct metal laser sintering, ultrasonic consolidation, wire arc additive manufacturing, and hybrid manufacturing. I believe that this Special Issue bears is vital to the field of AM and will be a valuable addition.
