Named after C.Y. HUI and H. RIEDEL who intensively studied creep crack growth this field is called Hui-Riedel field. In contrast to the situation of a stationary crack (HRR-field) the stresses and strains of the Hui-Riedel field display ...
An equation for the toughness versus constraint relationship that was developed by Wallin [4], based on finite-element analyses of Anderson and Dodds [5] for a steel of Ramberg-Osgood work hardening exponent n = 10, is given as follows: ...
The material included in this book is based upon the development of analytical and numerical procedures pertinent to particular fields of linear elastic fracture mechanics (LEFM) and plastic fracture mechanics (PFM), including mixed-mode ...

Crack growth during a given hold time , aac , was calculated as the difference between the nine - point averages for the initial and final position of the hold time crack . The reasons for the discrepancies between Aa , and Aa , are the ...
Results and Discussion The results of testing were a series of curves representing crack growth rate versus high frequency K range for constant low frequency cycle AK range and low cycle hold time. Crack growth rate is reported in terms ...
Reflecting the many advances made in the decade since the previous edition came about, this indispensable Third Edition now includes: A new chapter on environmental cracking Expanded coverage of weight functions New material on toughness ...
These new challenges motivated the author to proceed with the second edition of the book. The second edition of the book contains four new chapters in addition to the ten chapters of the first edition.
From leading experts in fracture mechanics, this new text provides new approaches and new applications to advance the understanding of crack initiation and propagation.
Fracture Mechanics: 12th Conference
These new challenges motivated the author to proceed with the second edition of the book. The second edition of the book contains four new chapters in addition to the ten chapters of the first edition.
Fracture Mechanics: Proceedings of the Eleventh National Symposium on Fracture Mechanics, Part 1
This text, which the author has used in a fracture mechanics course for advanced undergraduate and graduate students, is based on the work of the author's Lehigh University team whose integrative research combined fracture mechanics, ...
This book is aimed at those in both industry and academic institutions who require a grounding not only in the basic principles of this important field but also in the practical aspects of evaluating fracture mechanics parameters.
The final chapter deals with the size effect with regard to extension of sharp cracks in technological materials. This book is a valuable resource for environmental and mechanical engineers.
In the Second Edition, about 30% of the material has been updated and expanded; new technology is discussed, and feedback from users of the first edition has been incorporated.
