DISLOCATION BASED FRACTURE MECHANICS

I would never have thought to have opened this book from its title, as I have never done research on fracture. I am strictly an electronic materials, nanomaterials, and thin films person. The author, however, addresses an mathematically intensive theoretical approach to understanding dislocation mechanics that is useful in a number of research applications.I saw this book referenced on a paper on dislocations in thin films [Zhu and Wu, Acta Mech 211, 271 (2010)] and decided to peruse it for the difficult topic of dislocations in a film with different mechanical constants than its substrate. This topic can also be seen as that of that of calculating the stress of a dislocation near an interface that separates two elastic half spaces of differing elastic constants. Screw, glide edge (where glide is parallel to the interface), and climb edge dislocations are addressed in section 2.11 on pp.93-93; and in Appendix C on pp.439-454. Section C explains the general method for stress fields of dislocations near an interface, a technique that is particular useful in dealing with the interface and free surface encountered in a thin film.This book is 524 pages long, with most of it indeed dedicated to fracture mechanics, especially as applied to cracks. Nevertheless, the generality of the techniques that the author describes prove useful in the understanding of diverse materials problems.
