Parameter Sensitivity in Nonlinear Mechanics: Theory and Finite Element Computations

[Image: 84756053085744885733.jpg]

[Image: info.png]
Editorial Reviews
There are various methods for the analysis and design of bodies subject to static and dynamic loadings in structural and solid mechanics. Sensitivity analysis is concerned with the relationship between parameters, describing the structure under consideration and the function describing the response of that structure under loading conditions. This book addresses the finite element computational techniques typical of sensitivity analysis for solid mechanics systems with any nonlinearity. It is an attempt to combine theoretical modelling techniques with effective computer implementation: besides the theory many suitable finite element codes have been developed by the authors and used for computing examples discussed in the text.

From the Publisher
Addressing nonlinear sensitivity problems in a consistent manner, this book analyses solid mechanics systems with any nonlinearity, such as large deformations, buckling and post-buckling, plasticity and viscoplasticity, nonlinear dynamics and nonlinear transient heat conduction. Beside the theory and results of numerical computations presented in the book, some finite element programs used for solving the examples .

Irrigation Management
By Martin Burton
* Publisher: CABI
* Number Of Pages: 392
* Publication Date: 2010-03-25
* ISBN-10 / ASIN: 1845935160
* ISBN-13 / EAN: 9781845935160

In many countries irrigated agriculture consumes a large proportion of the available water resources, often over 70% of the total. There is considerable pressure to release water for other uses, and as a sector irrigated agriculture will have to increase its efficiency and productivity of water use. Drawing on the author's 30 years of experience in some 28 countries, this book offers knowledge for the management of irrigation and drainage systems, including traditional technical areas of systems operation and maintenance, and expanding managerial, institutional and organizational aspects. Chapters provide guidelines to improve management, operation and maintenance processes, which move management thinking out of traditional public-sector mindsets to a more customer-focussed, performance-oriented service delivery. As a practical guide to improve efficiency and productivity in irrigated agriculture, this book will be essential reading for irrigation managers and technicians as well as students and policymakers in water management, agriculture and sustainable development.

  Structural Sensitivity Analysis and Optimization: Choi, Kim
Posted by: NAUTILUS87 - 05-08-2010, 08:47 PM - Forum: Analysis & Design - Replies (8)

Structural Sensitivity Analysis and Optimization volume 1 & 2

[Image: info.png]
Structural design sensitivity analysis concerns the relationship between design variables available to the design engineer and structural responses determined by the laws of mechanics. The dependence of response measures such as displacement, stress, strain, natural frequency, buckling load, acoustic response, frequency response, noise-vibration-harshness (NVH), thermo-elastic response, and fatigue life on the material property, sizing, component shape, and configuration design variables is defined through the governing equations of structural mechanics. In this 2-volume set, first- and second- order design sensitivity analyses are presented for static and dynamics responses of both linear and nonlinear elastic structural systems, including elasto-plastic and frictional contact problems.

BRIDGES: The Science and Art of the World’s Most Inspiring Structures
Oxford University Press, USA | March 1, 2010 | ISBN-10: 0199543593 | 288 pages | PDF | 2.4 mb

In this fascinating exploration for lay readers, Blockley lucidly explains both the basic forces at work on every bridge—tension, compression, and shear—and the structural elements combating those forces: beams, arches, trusses, and suspension cables. He succeeds in his desire to read a bridge like a book.

Editorial Reviews

The author is to be congratulated on the large number of examples he cites, drawn from many parts of the world and with excellent UK representation. Geographical Association 2/01

Although dealing with highly complex phenomena, the content of this volume is readily accessible by non-specialists, those in management roles, or those generally seeking a better understanding of geohazard phenomena. The Australasian Journal of Disaster and Trauma Studies Volume 2001/2

The discussion of hazards is both Comprehensive and critical and Bell does a good job of clarifying the complexity and uncertainty inherent in the study of geohazards. This critical focus further enhances the utility of this volume as an aid to comprehensive all-hazards planning. The Australasian Journal of Disaster and Trauma Studies Volume 2001/2

...an essential resource for those in emergency management and planning. The Australasian Journal of Disaster and Trauma Studies Volume 2001/2

...an excellent and accessible review of diverse hazard phenomena and one that should be regarded as essential reading for anyone requiring a detailed and comprehensive summery of hazard phenomena and who is grappling with the complexities of developing all-hazards plans and response capabilities. The Australasian Journal of Disaster and Trauma Studies Volume 2001/2

Geological Hazards is a welcome and valuable addition to the literature covering this subject. Its wide and balanced approach to the subject will be of great use to educators, researchers and planners and fills a clear gap in the subject. It is very well written and as an accessible and informative text interested undergraduates will read it avidly. The Geographical Journal 2002

  PCI: Tolerance Manual for Precast and Prestressed Concrete Construction
Posted by: robertsas - 05-08-2010, 08:39 AM - Forum: Concrete - No Replies

Tolerance Manual for Precast and Prestressed Concrete Construction - PCI

[Image: info.png]
This new reference manual is intended to assist designers, producers and erectors of products for the building industry in determining the proper tolerances in every phase of the building process. The new manual contains information vital to architects, engineers, general contractors, precast and prestressed concrete producers, quality control agencies and other interfacing building trades. In a preface to its comprehensive volume, the PCI Committee On Tolerances says, in part, ""It is essential that the members of the building team collaborate to provide an overall project tolerance system which will meet all of the project's functional needs and allow economical fabrication and erection for the precast concrete members and all of the interfacing building systems."" To accomplish those objectives, the new manual contains a wealth of information covering both plant-cast and site-cast precast and precast prestressed concrete. The committee warns, however, that the tolerances defined in the manual are designed to provide a reference point, not be rigid and unyielding. The tolerances contained within the manual are based on current modern precast concrete production techniques. The report preface points out that its intent is to provide the tools to enable the party responsible for tolerances to develop a tolerance plant that will lead to a successful project. The nearly 200-page manual defines the custom nature of building construction, defines tolerance categories, identifies tolerance issues, discusses responsibility for project dimensional control and describes mechanisms for handling tolerance discrepancies. Other sections of the document deal with a variety of issues, beginning with definition of tolerance related terms, relationships among various tolerance groups, product tolerances, special tolerance considerations, individual product tolerance listings, erection tolerances, mixed building system erection tolerances, clearance considerations, interfacing tolerances, design approaches for interfacing tolerance systems and characteristics of a tolerance interface. Later sections in the manual include a variety of typical tolerance related details as well as examples of tolerance detailing related calculations. Appendices provide the reader with examples of specification language and even sample contract language. The new publication complements and supports two other previously published PCI quality control manuals. These include MNL-116 Manual for Quality Control for Plants and Production of Precast and Prestressed Concrete Products and MNL-117 Manual for Quality Control for Plants and Production of Architectural Precast Concrete Products. The three documents form the basis of quality design and quality fabrication and erection for Precast and Prestressed Concrete Products. The new manual is designated MNL 135-00.
