This nice and comprehensive title is specifically intended to clearly describe the matters relating to the NDE, standing for the non-destructive evaluation, and commonly associated with the real-life applications of the NDE methods, detailing both existing, i.e. conventional plus also the forthcoming techniques of such evaluation. Through the content of his work, the author is instructing readers on the current practices, commonly used techniques and equipment in use, together with the limitations and future potentials of the existing methods of evaluation.
Each chapters is detailing a particular NDE method, providing a comprehensive technical overview and clear explanation of the basic physical laws that are governing this method, covering also the inspection techniques. The authors are also discussing some historical background of each of the methods covered. The equations used for calculating have also been dealt with. It is a really perfect source of reference info for people willing to get better understanding of the techniques.
The book shall be equally useful for the students and specialists since the information is presented in a very simple and clear language; the authors have managed to prepare an excellent blend of the fundamental and advanced information addressing the most popular non-destructive testing.
The publication starts with the introductory information followed by the historical background of the metal fatigue factor including the experimental works, standardization, fracture mechanics, implementation of the computers and servo-hydraulic testing appliances. The next chapter addresses the constant amplitude metal fatigue, including the fatigue mechanisms, ratcheting, S/N curves etc.
This one is followed by the chapter dedicated to the variable amplitude and multi-axial metal fatigue, including the math description, Miner's rule, standard load histories and other relevant information. The fifth chapter is dealing with the fatigue design, covering the failure analysis, approaches and situations, product liability and associated safety regulations. The next chapter addresses the uncracked situation, including the surface finish and mean stress effects, effects of notches, fatigue life improvement etc., while the following chapter addresses the cracked situation including the initial and final crack sizes, crack propagation, interaction effects, fractography and other important factors.
The remaining chapters of the book are dedicated to the fatigue crack paths, researches and development in the field, current industry trends, avoidance of the failures etc. Three appendices provide the information about the fracture mechanics, non-destructive tests, and random load theory.
The publication is presenting the updated view of the marine corrosion of the stainless steel, covering the relevant fields of selection and testing of the materials, their protection and monitoring. The first part of the volume consists of five chapters and is mainly concerned with the analysis of the results of the tests conducted in the course of the researches performed in the European sea waters towards the three popular types of the stainless steel some thirty years ago.
The author of the book has provided the clear description of the experimental procedures and all required data, such as the critical pitting temperature, as well as the crevice corrosion results etc. This information is forming the core of the volume, followed by the chapters dealing with the professional reviews of the results and reports. The main covered topics are the selection of the materials, including superaustenic steels, desalination processes, high-alloy steels, topside marine corrosion, duplex stainless steels and other important matters.
The chapter addressing the testing and experience covers the application limits, steel ageing and its influence on the behavior, modern steels, potential-dimension diagram, nickel base alloys etc. The "protection and monitoring" chapter covers the cathodic protection, monitoring of the pitting corrosion, future applications and other aspects.
The preparation of the content of this third release of the Handbook nearly ten years after the release of the original one, required a full revision of the major portion of the book, not only because of the recent technical developments that occurred in technology and application, but also because of the identification of the critical factors in the protection systems.
The authors has also taken into account the developments in the recognized standards and commonly applicable regulations. The electro-chemical corrosion and associated corrosion protection are based on the same foundation. The scientific basis of the present volume has been formed by the uniform terminology provided in the DIN 219 manual. Our understanding of the problem has been significantly improved thanks to the descriptions of the newly developed systems of protection and questions related to the utilization of the current and potential distribution plus the influence of the high tension.
There are some serious advances in the IR-free potential measurement, data evaluation and intensive measuring techniques. The publication is highly recommended to the people dealing with the prevention of corrosion of the ship hulls, i.e. workers of the ship construction and repair industries who will definitely appreciate the content of the volume.
It is well known from the marine history that from the first steps done in the navigation, the marine fouling, i.e. growth of various aquatic organisms on the ships underwater parts was always treated as a very serious problem. This book is aimed to address some key aspects of the technologies of development and application of the anti-fouling coatings intended to protect the ships hull.
The following aspects are covered in this volume: Marine fouling organisms, their impact on the hull, chemically active marine antifouling technologies, development of antifouling coatings and their testing, various surface approaches to the control of marine bio-fouling.
