Deformation and Fracture Mechanics of Engineering Materials 5ed
Section 1 : The principles of elastic and plastic
deformation are presented.
Chapter 1 begins with a discussion of elastic deformation in solids, concepts of stress, strain, and stiffness are introduced for both isotropic and anisotropic materials. Chapter 2 addresses the plastic deformation response of solids. Here, emphasis is placed on continuum aspects of irreversible plastic deformation and the role of micro and nanostructures, crystallography, and crystal defects (e.g. dislocations) in explaining the material deformation process. Subsequently, these parameters are used in Chapter 3 to understand various strengthening mechanisms in different material systems. The time temperature dependent nature of material deformation in metallic, ceramic, and polymeric materials is addressed in Chapter 4, while familiarity with the topics discussed in section one will be useful to the reader ins Section Two, readers with some prior exposure to mechanical behavior concepts may be able to proceed directly from Chapter 1 to chapter 5.
Section 2 : Deals with the application of fracture
mechanics principles to the subject of
fracture in solids.
Chapter 5 begins with an overview of failed components, and discusses stress concentrations and theoretical fracture strength, notch strengthening, statistical aspects of fracture and fracture surface micromorphology. The importance of the stress intensity factor and the fracture mechanics approach in analyzing the fracture of solids is developed in Chapter 6 and is compared with the older transition temperature approach to engineering design. From this macroscopic viewpoint, the emphasis shifts in Chapter 7 to a consideration of the role of micro- and nanostructural variables in determining material fracture toughness and embrittlement susceptibility, such as temper, irradiation, and 300 derajat C embrittlement. Environmental degradation (i.e., stress corrosion cracking and both hydrogen and liquid metal embrittlement) is described in Chapter 8 in terms of stress environment material systems. Fatigue and associated crack propagation in solids is discussed at length in Chapters 9 and 10, emphasizing the cyclic stress life, cyclic strain life, and fatigue crack propagation philosophies pertaining to cyclically induced material damage. In Chapter 11, actual service failures are examined to demonstrate the importance of applying fracture mechanics principles in failure analysis. Several bridge, aircraft, firearm, and generator rotor shaft failures are analyzed. Finally, the consequences of component failure are introduced in Chapter 12 with a discussion of product liability and product recall.
