Engineering Materials-1: An Introduction to their Properties and Applications (Second Edition)

particular application, but not necessarily (although sometimes) new in the sense of ‘recently developed’. Plastic paper clips and ceramic turbine-blades both represent attempts to do better with polymers and ceramics what had previously been done well with metals. And engineering disasters are frequently caused by the misuse of materials. When the plastic tea-spoon buckles as you stir your tea, and when a fleet of aircraft is grounded because cracks have appeared in the tailplane, it is because the engineer who designed them used the wrong materials or did not understand the properties of those used. So it is vital that the professional engineer should know how to select materials which best fit the demands of the design - economic and aesthetic demands, as well as demands of strength and durability. The designer must understand the properties of materials, and their limitations.
This book gives a broad introduction to these properties and limitations. It cannot make you a materials expert, but it can teach you how to make a sensible choice of material, how to avoid the mistakes that have led to embarrassment or tragedy in the past, and where to turn for further, more detailed, help.
You will notice from the Contents list that the chapters are arranged in groups, each group describing a particular class of properties: the elastic modulus; the fracture toughness; resistance to corrosion; and so forth. Each such group of chapters starts by defining the property, describing how it is measured, and giving a table of data that we use to solve problems involving the selection and use of materials. We then move on to the basic science that underlies each property, and show how we can use this fundamental knowledge to design materials with better properties. Each group ends with a chapter of case studies in which the basic understanding and the data for each property are applied to practical engineering problems involving materials. Each chapter has a list of books for further reuding, ranked so that the more elementary come first. At the end of the book you will find sets of examples; each example is meant to consolidate or develop a particular point covered in the text. Try to do the examples that derive from a particular chapter whilesthis is still fresh in your mind. In this way you will gain confidence that you are on top of the subject.
