Introduction to Finite Elastoplasticity presents introductory explanations that can be readily understood by readers with only a basic knowledge of elastoplasticity, showing physical backgrounds of concepts in detail and derivation processes of almost all equations. The authors address various analytical and numerical finite strain analyses, including new theories developed in recent years, and explain fundamentals including the push-forward and pull-back operations and the Lie derivatives of tensors.
As a foundation to finite strain theory, the authors begin by addressing the advanced mathematical and physical properties of continuum mechanics. They progress to explain a finite elastoplastic constitutive model, discuss numerical issues on stress computation, implement the numerical algorithms for stress computation into large-deformation finite element analysis and illustrate several numerical examples of boundary-value problems. Programs for the stress computation of finite elastoplastic models explained in this book are included in an appendix, and the code can be downloaded from an accompanying website.

Author: Patrick Paultre | Size: 12 MB | Format:PDF | Quality:Unspecified | Publisher: ISTE Ltd and John Wiley & Sons | Year: 2011 | pages: 802 | ISBN: 9781848210639
This book covers structural dynamics from a theoretical and algorithmic approach. It covers systems with both single and multiple degrees-of-freedom. Numerous case studies are given to provide the reader with a deeper insight into the practicalities of the area, and the solutions to these case studies are given in terms of real-time and frequency in both geometric and modal spaces. Emphasis is also given to the subject of seismic loading.
The text is based on many lectures on the subject of structural dynamics given at numerous institutions and thus will be an accessible and practical aid to students of the subject.
Key features:
> Examines the effects of loads, impacts, and seismic forces on the materials used in the construction of buildings, bridges, tunnels, and more
> Structural dynamics is a critical aspect of the design of all engineered/designed structures and objects - allowing for accurate prediction of their ability to withstand service loading, and for knowledge of failure-causeing or critical loads

We are very pleased to offer you our free study guide (PDF document) entitled “Practical Aspects of Finite Element Simulation“.
We feel that the content of the book makes a difference to the many books about FEA available in the market. We deliberately kept the maths behind FEA at its minimum but rather addressed questions such as:
What is needed to run a Finite Element Analysis
Strategic Planning
Modeling – Common mistakes and errors
Aspects of meshing
Element quality and checks
Boundary conditions and loads
Aspects of postprocessing
and others.

This book is based on a number of lectures presented at CISM* -Course on "Stochastic Methods in Structural Mechanics", August 28 -30,1985 in Udine, Italy. The chapters presented here are either expanded and/or updated versions of these lectures. The purpose is to introduce readers to basic principles of stochastic methods of structural mechanics, particularly to those of dynamics. For those readers who wish to pursue the study further, the references provided in each chapter will serve as a useful source of information. Nevertheless the readers find some of the advanced topics presented by the authors immediately useful for their own application. The first section of Chapter 1 introduces the reader to the basic principles of probability theory followed by the discussion of methods to calculate time invariant structural reliability estimates, where the exact methods are particularly emphasized. The Chapter continues with a first introduction to the theory of stochastic processes. The properties of Gaussian and other type of processes are discussed. In dealing with observed data, tests of stationarity, as well as methods to estimate power spectra are described in some detail. The Chapter closes with a first treatice of excursions of stochastic processes in terms of number and duration of excursions, extremes, envelopes and time to first excursions. In Chapter 2 linear structures under stochastic loading are analyzed by applying the concepts as outlined in Chapter 1. The analyses are carried out in the time and frequency range respectively.

CONCRETE INTERNATIONAL is the monthly magazine of the American Concrete Institute and is circulated to engineers, architects, contractors, manufacturers, and technicians responsible for the design, construction, and testing of concrete applications throughout the world. Many of the magazine’s readers and contributors also collaborate in preparing ACI codes and standards and are therefore leaders in the advancement of concrete as a construction material.

This book is a pioneering classic in the philosophy of structural engineering, focusing on structural design and safety. David Blockley's erudition is considerable, especially for an engineer, and the book is greatly enriched by it. More specifically, Blockley draws on philosophical, historical, sociological, scientific, and mathematical perspectives in order to thoroughly and deeply examine the nature and basis of structural engineering practice. The result is a wide ranging book which is both informative and enjoyable.

The Third Edition of this publication has become the leading guide for student engineers and is used widely on engineering courses throughout the United Kingdom and beyond. The book gives information on common design principles and rules for the design of structures and component products. It also describes a common series of methods for calculating the structural strength of elements used in construction. It contains extracts from some of the principal parts of each of the Eurocodes. The extracts chosen are as concise as possible, focusing on the essential principles in the Eurocodes. Commentary is kept to a minimum and only made on parts of the text that require explanation. This is a user-friendly guide that introduces the principles of structural Eurocodes to students of civil engineering, structural engineering and structural design. It would also be useful guidance for anyone working in the construction industry.

Some Research Results on Bridge Health Monitoring, Maintenance and Safety III
Author: Yang Liu | Size: 15 MB | Format:PDF | Quality:Original preprint | Publisher: Trans Tech Publications Ltd | Year: 2014 | pages: 214 | ISBN: 978-3-03785-817-2
The amount of deteriorating bridges is increasing gradually, and the costs of maintenance, repair and rehabilitation of these bridges often far exceed available budgets. To alleviate this issue, the bridge engineering profession continues to take positive steps towards developing more comprehensive bridge monitoring and management systems. This collection of invited papers encompasses some aspects of bridge health monitoring, maintenance and safety. Specifically, it deals with: bridge health monitoring; bridge repair and rehabilitation issues; bridge related safety and other implications.
