Materials are considered critically important elements that support different technological areas. The toughness and strength of materials are their basic mechanical characteristics. To realize them, it is imperative to duly clarify the mechanism of fracturing. The content of this title summarizes the results of the research works conducted in the labs forming a foundation of the laboratory principle. It will be useful for the undergraduate and graduate students, practicing materials engineers and researchers. The volume opens with the introductory chapter generalizing the major points of toughness and strength of materials to state the background of the title outline and constitution. The next two chapters provide the information about the fundamental concepts of the fracture mechanics and main theoretical principles of toughness and strength of the materials. There is a separate chapter dedicated to steels covering the solid state transformation, correlations among different characteristics, steel degradation, carburized steel etc. This one is followed by the chapters addressing the ductile cast iron and wrought aluminum alloys including their features at deformation, cast aluminum alloys and metal matrix composites. Remaining chapters cover the inter-metallic compounds, polymeric and ceramic materials...
The present training booklet has been specifically designed by Videotel company with the intention to provide the crew members and all other people dealing with the use of the abrasive wheels with all necessary information and safety precautions to be taken. The book starts with the short introduction followed with the practical tips for the storage and maintenance of subject equipment, and keeping the wheels in good operational and working condition - starting from making the right choice when selecting the wheel and checking the markings on the wheel and manufacturer's code. The next chapter is dedicated to the actual use of the wheels, starting from the preparation of the wheels for work an checking their condition and fitness, through mounting the wheel onto portable and static machines, basic safety matters and equipment used for provision of the safe work, safety precautions to take and safety measures to be implemented and followed to make the work safe, and also main do's and don'ts to be considered when using the portable machines. Then there is a summary of the information provided in the booklet and several question for assessment of your understanding. Appendices contained in the last section of the booklet provide the legislation-related information, useful case studies and further resources to check.
A vessel at open sea fully depends on the professional knowledge, technical skills and also self-reliance of the crew members carrying out required maintenance and repair works. Among the other important technical skills that are considered necessary, we would mention the modern welding techniques. The ultimate purpose of the present training handbook prepared by the specialists of the Unitor Company specifically for the maritime welders was to provide the welders engaged in different ship building and ship repair works with the useful source of practical knowledge covering the right solutions to the specific problems of the welding. The document opens with the quick introduction and guidance to the welding processes. The process of welding and other related thermal processes are using compressed either compressed gas or electricity to get a concentrated heat source melting or burning away steel and other construction materials. All necessary safety precautions are required to be in place and followed in order to avoid any possible accidents relating to the supply of gas/electric power, sparks and fumes etc. In the most countries, the regulations and guidelines relating to the welding and any other hot works together with their applications onboard vessels, are laid down by the authorities.
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.
