Non-Linear Finite Element Analysis in Structural Mechanics


Book Description

This monograph describes the numerical analysis of non-linearities in structural mechanics, i.e. large rotations, large strain (geometric non-linearities), non-linear material behaviour, in particular elasto-plasticity as well as time-dependent behaviour, and contact. Based on that, the book treats stability problems and limit-load analyses, as well as non-linear equations of a large number of variables. Moreover, the author presents a wide range of problem sets and their solutions. The target audience primarily comprises advanced undergraduate and graduate students of mechanical and civil engineering, but the book may also be beneficial for practising engineers in industry.




Knowledge Base - Don't Forget the Basics


Book Description

In October 2003, NAFEMS began to publish a series of articles in benchmark magazine, aimed at covering a number of basic FEA principals in a readable and useful format. This “knowledge base” series continued to run over the next seven years, based on the principal that it is always useful to reinforce basic concepts and theories, no matter how advanced the user of the technology has become. In that time, topics as diverse as mesh convergence, pressure vessel stresses, and fatigue have been covered by the author, Mark Chillery of Chalice Engineering. The aim has always been to outline the basic theories behind each topic, and give the reader a quick “one-page” refresher on the subject matter, without delving too deeply into the specifics of the area being covered. After around 23 articles spanning many aspects of FEA, it was decided that the series itself had run its course, but that the material produced could provide great value to analysts by being put together in one reference manual, which could be used as a day-to-day guide to the basics of some of the engineering analysts most critical areas of work. And so this ‘compilation’ has now been produced in order to bring these articles together in an accessible and user-friendly format, which we hope will prove invaluable as an initial reference into a multitude of topics. The articles themselves do not claim to be “definitive” guides to each topic, nor are they the only manner in which some of the analysis processes defined can be carried out – rather they are written from the perspective of an experienced analyst, working with the technology day in, day out. This compilation also differs from many NAFEMS publications, in that the articles have not been extensively edited by the NAFEMS technical working groups. Each article itself could be developed into a publication many times the length of the original by going through this process, but the aim of the articles is not to provide an all-encompassing view of the topic being covered, rather, they should be treated as an introduction to the basics, to underpin basic concepts, and inspire further reading. We hope you find the book useful, and that it helps in some way towards reinforcing some technical knowledge that you use in your everyday work. As the byline says - “Don’t Forget the Basics...”




Proceedings of 1st International Conference on Structural Damage Modelling and Assessment


Book Description

This book comprises the select proceedings of Structural Damage Modelling and Assessment (SDMA 2020) presented online on 4–5 August 2020. It discusses the recent advances in fields related to damage modelling, damage detection and assessment, non-destructive testing and evaluation, structure integrity and structural health monitoring. The conference covers all research topics and applications relevant to structural damage modelling and assessment using theoretical, numerical and experimental techniques. This book is useful to scientists and engineers in academia and industry who are interested in the field of structural damage and integrity.




Buckling and Post Buckling Structures


Book Description

This book provides an in-depth treatment of the study of the stability of engineering structures. Contributions from internationally recognized leaders in the field ensure a wide coverage of engineering disciplines in which structural stability is of importance, in particular the analytical and numerical modelling of structural stability applied to aeronautical, civil, marine and offshore structures. The results from a number of comprehensive experimental test programs are also presented, thus enhancing our understanding of stability phenomena as well as validating the analytical and computational solution schemes presented. A variety of structural materials are investigated with special emphasis on carbon-fibre composites, which are being increasingly utilized in weight-critical structures. Instabilities at the meso- and micro-scales are also discussed. This book will be particularly relevant to professional engineers, graduate students and researchers interested in structural stability.




Buckling And Postbuckling Structures Ii: Experimental, Analytical And Numerical Studies


Book Description

This book provides an in-depth treatment of the study of the stability of engineering structures. Contributions from internationally recognized leaders in the field ensure a wide coverage of engineering disciplines in which structural stability is of importance, in particular the experimental, analytical and numerical modelling of structural stability applied to aeronautical, civil and marine structures. This second volume in buckling and postbuckling structures builds on the first, and reports on the development of fast semi-analytical methods for the rapid characterization of postbuckling structures; optimization approaches for the design of stiffened composite panels, and a discourse on imperfection sensitivity. This book will be a particularly useful reference to professional engineers, graduate students and researchers interested in structural stability.










Buckling of Shells


Book Description

Thin shells are very popular structures in many different branches of engineering. There are the domes, water and cooling towers, the contain ments in civil engineering, the pressure vessels and pipes in mechanical and nuclear engineering, storage tanks and platform components in marine and offshore engineering, the car bodies in the automobile industry, planes, rockets and space structures in aeronautical engineering, to mention only a few examples of the broad spectrum of application. In addition there is the large applied mechanics group involved in all the computational and experimental work in this area. Thin shells are in a way optimal structures. They play the role of·the "primadonnas" among all kinds of structures. Their performance can be extraordinary, but they can also be very sensitive. The susceptibility to buckling is a typical example. David Bushnell says in his recent review paper entitled "Buckling of Shells - Pitfall for DeSigners": "To the layman buckling is a mysterious, perhaps even awe inspiring phenomenon that transforms objects originally imbued with symmetrical beauty into junk".
