Description

Fatigue of Metals provides a general account of the failure of metals due to fatigue, a subject of great practical importance in the field of engineering and metallurgy. The book covers a wide range of topics on the study of the fatigue of metals. The text presents in the first three chapters the characteristics and detection of fatigue fractures; methods of fatigue testing; and the fatigue strengths of different materials. The resistance of materials to fatigue under complex stress; the determination and effects of stress concentration; influence of surface treatment on fatigue strength; and effects of corrosion and temperature are also studied in detail. In relation to the previous chapters of fatigue information, a chapter is devoted to engineering design to prevent fatigue. The last two chapters provide a brief historical survey of the developments of the study of the mechanism of fatigue and fatigue of non-metallic materials such as wood, plastic, rubber, glass, and concrete. Mechanical engineers, designers, metallurgists, researchers, and students will find the book as a good reference material.
