Applied mechanics of materials

Abstract

Components and structures in mechanical and civil engineering are made of various materials, and design engineers must have a good knowledge of their mechanical properties. This book deals with this area. The first chapter summarises the principal terms: stress, strain, and strain energy. The second chapter compares the finite element method and analytical methods for the determination of stresses and deformations. Chapter 3 presents the principal criteria for fracture and for the onset of permanent deformations. The following chapter is devoted to plastic deforming. Attention is also paid to thermal stresses. Chapter 6 deals with stress concentration at sudden changes of shape. Chapters on fatigue, fracture mechanics and analysis of fractures follow. Chapter 10 explains the mechanics of viscoelastic materials, whose deformations depend on the duration and time course of loading. The following chapters are devoted to components with treated or coated surfaces, to the properties of composite materials and of elastomeric materials. The methods of shape optimisation for improvement of strength and material economy are the topic of Chapter 14. The last chapter is devoted to the theory of similarity and dimensional analysis and their use for increasing the design effectiveness. The book contains numerous figures and examples, which illustrate the use of the described methods.
