These are the papers presented at the Fib-RILEM workshop held in Madrid, Spain, in November 2010. The assessment of deterioration and aging of concrete structures, most commonly through reinforcement corrosion, is not considered in current structural codes or standards. Some guidelines manuals exist, and research has been done, but there is as yet no accepted methodology nor models that could be used by engineers.
This book deals with all aspects related to modelling of corroding structures and provides state-of-the-art information on structural models for corroding structures.

Hi All,
I just received this Texas Instrument 89 series, and its so unbelievably true that it comes along with a 325 page tutorial book!!
Please I request from those who may be familiar with these models of calculators to avail on the forum , if they have, a TI-89 CALCULATOR TUTOR DVD VOL.1 By Jason Gibson 3-DVDs, or any other in their possession. It may be easier to go about with the DVD tutorials.
Fatigue damage in a system with one degree of freedom is one of the two criteria applied for the comparison of severity of many vibratory environments. This criterion is also employed for a specification representing the effects produced by the set of vibrations imposed in useful life. In this volume, which is devoted to the calculation of fatigue damage, the hypotheses adopted to describe the behaviour of material suffering fatigue and the laws of fatigue accumulation are explored. Also considered are the methods of counting the response peaks, which are used to establish the histogram when it is impossible to use the probability density of the peaks obtained with a gaussian signal. The expressions for means damage and its standard deviation are established, and other hypotheses tested.

Micromechanisms of Fracture and Fatigue forms the culmination of 20 years of research in the field of fatigue and fracture. It discusses a range of topics and comments on the state of the art for each.
The first part is devoted to models of deformation and fracture of perfect crystals. Using various atomistic methods, the theoretical strength of solids under simple and complex loading is calculated for a wide range of elements and compounds, and compared with experimental data. The connection between the onset of local plasticity in nanoindentation tests and the ideal shear strength is analysed using a multi-scale approach. Moreover, the nature of intrinsic brittleness or ductility of perfect crystal lattices is demonstrated by the coupling of atomistic and mesoscopic approaches, and compared with brittle/ductile behaviour of engineering materials.
The second part addresses extrinsic sources of fracture toughness of engineering materials, related to their microstructure and microstructurally-induced crack tortuosity. Micromechanisms of ductile fracture are also described, in relation to the fracture strain of materials. Results of multilevel modelling, including statistical aspects of microstructure, are used to explain remarkable phenomena discovered in experiments.
In the third part of the book, basic micromechanisms of fatigue cracks propagation under uniaxial and multiaxial loading are discussed on the basis of the unified mesoscopic model of crack tip shielding and closure, taking both microstructure and statistical effects into account. Applications to failure analysis are also outlined, and an attempt is made to distinguish intrinsic and extrinsic sources of materials resistance to fracture.
Micromechanisms of Fracture and Fatigue provides scientists, researchers and postgraduate students with not only a deep insight into basic micromechanisms of fracture behaviour of materials, but also a number of engineering applications.

Plate Tectonics: Continental Drift and Mountain Building
Author: Frisch Wolfgang, Meschede Martin, Blakey Ronald C. | Size: zip 117 MB | Format:PDF | Publisher: Springer | Year: 2011 | pages: 217 | ISBN: 978-3-540-76503-5
* Presents many examples from North America and around the World
* Includes over 190 excellent full colour diagrams and maps
How are mountains formed? Why are there old and young mountains? Why do the shapes of South America and Africa fit so well together? Why is the Pacific surrounded by a ring of volcanoes and earthquake-prone areas while the edges of the Atlantic are relatively peaceful?
Frisch and Meschede and Blakey answer all these questions and more through the presentation and explanation of the geodynamic processes upon which the theory of continental drift is based and which have led to the concept of plate tectonics.

Industrial Wastewater Treatment
Author(s): Ng Wun Jern (National University of Singapore)
Publisher: mperial College Press
Date: 2006 Format: pdf
Language: English
ISBN10: 1860945805
Pages: 164
Size: 11.50 MB
This book adopts a “show and tell” approach to guiding readers in the area of industrial wastewater treatment and the facilities associated with such treatment. It assumes the reader is familiar with wastewater treatment theory but may be unfamiliar with the reasons why certain unit processes or equipment are included in practice, how these work, and why they fail therein. Industrial wastewaters are extremely varied and this complicates their treatment and discussion. Numerous tables showing industrial wastewater characteristics and photographs of facilities are provided so that the reader can better appreciate industrial wastewater treatment and its “culture” in Asia, and gain a degree of familiarity with the subject unachievable if only text descriptions were used. The book aims to provide a link between theory and practice. It does not only cover typical textbook material but also includes much information that would usually be accessible only to persons who have handled wastewaters and treatment facilities personally. The numerous examples provided have been drawn from the author's own field experience over two decades in Asia.
