Springer Multiscale Fatigue Crack Initiation and Propagation of Engineering Materials: Structural Integrity and Microstructural Worthiness: Fatigue Crack ... (Solid Mechanics and Its Applications, 152)

This book elucidates the correlation of fatigue crack growth data to multiscale cracking, particularly to the understanding of micrographs influenced by mechanical disturbance and thermodynamic variables. From the Back Cover This book elucidates the correlation of fatigue crack growth data to multiscale cracking, particularly to the understanding of micrographs influenced by mechanical disturbance and thermodynamic variables. Attention is given to the interpretation of test data by fatigue crack growth rate using two empirical parameters in consistence with the fracture control methodology currently used by industry. Micrograph and crack growth rate data are presented for a host of metals used by the aerospace and nuclear industry. Furthermore, these data can be shown to lie on a straight line for the two parameter model that traditionally refers to regions I, II, and III. Results for small and large cracks can thus be connected to provide fatigue life prediction with data from the microscopic scale level such that the interactive effects of loading, geometry and material by mechanical tests are accounted for. About the Author Dr. George C. M. Sih Visiting Professor of Mechanical Engineering East China University of Science and Technology, Shanghai 200237, China Visiting Professor of Institute of Mechanics Chinese Academy of Sciences, Beijing 100080, China and Emeritus Professor of Mechanics and Director of the Institute of Fracture and Solid Mechanics Lehigh University, Bethlehem PA 18015, USA Dr Sih is currently a Visiting Professor in the Department of Mechanical Engineering at the East China University of Science and Technology, Shanghai, China. He is also a Visiting Professor of the Institute of Mechanics at the Chinese Academy of Sciences in Beijing, China. He served as Director of the Institute of Fracture and Solid Mechanics at Lehigh University, Bethlehem PA. USA. Dr Sih received his B. S. at the University of Portland, Oregon, 1953; his M. S. at New York University, 1958; and his Ph.D. at Lehigh University, 1960, all of which are in Mechanical Engineering. Dr. Sih served as Visiting Professor in USA, Europe and Asia. Among the universities are: . Aeronautics at the California Institute of Technology, Pasadena, California, USA 0 Hahnemann Medical College and Hospital of Philadelphia, PA, USA . Mechanical and Aeronautical Engineering at University of Patras, Patras, Greece Dr. Sih has also served as Consultants and Principle Investigators to the following companies and US government agencies: Administration In his earlier research works, Dr. Sih was involved with the development of high performance and design of materials by making use of the discipline of "Fracture Mechanics". He specializes in computer simulation of the mechanical behavior of structures and the aerodynamic stability of solids moving through fluid media. This includes the transonic-fiutter of airfoils; high speed projectile/target penetration; non-destructive testing methods, etc. His more recent activities are concerned with the theories of nonequilibrium thermomechanics applied to scaling of size, time and temperature effects for nanomaterials. His more recent interest has been involved with the aging of polymeric (and metallic) materials where chemical reactions would alter the structural arrangements of the molecules owing to specimen size, time and temperature effects. Much of his recent publications have been associated with "mesomechanics" in an attempt to understand how hetero-structures due to imperfections at the nano- and meso-scale would affect material behavior at the macroscopic scale. Dr. Sih has organized more than 30 international conferences, published 8 books and more than 380 technical papers. He has memberships to many professional societies in addition to being the recipient of awards from technical societies. Recent publications: [1] G.C. Sih , Implication of scaling hierarchy
