Fracture mechanics is a vast and growing field. This book develops the basic elements needed for both fracture research and engineering practice. The emphasis is on continuum mechanics models for energy flows and crack-tip stress- and deformation fields in elastic and elastic-plastic materials. In addition to a brief discussion of computational fracture methods, the text includes practical sections on fracture criteria, fracture toughness testing, and methods for measuring stress intensity factors and energy release rates. Class-tested at Cornell, this book is designed for students, researchers and practitioners interested in understanding and contributing to a diverse and vital field of knowledge.
The book introduces and informs the reader on how fracture mechanics works and how it is so different from other forms of analysis that are used to characterize mechanical properties.
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 ...
This book presents recent advances related to the following two topics: how mechanical fields close to material or geometrical singularities such as cracks can be determined; how failure criteria can be established according to the ...
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.
Intended for engineers, researchers, and graduate students dealing with materials science, structural design, and nondestructive testing and evaluation, this book represents a continuation of the author's "Fracture Mechanics" (1997).
Thus , it is assumed that p ( x ) = Ко 23 2пх for 0 < x < ut , ( 6.4.36 ) where Ko is the initial equilibrium stress intensity factor . The dynamic stress intensity factor for this case is ut Ко Kj ( ut , v ) = k ( u ) k ( w ) 6.
This book will be especially useful for students in mechanical, civil, industrial, metallurgical, aeronautical and chemical engineering, and for professional engineers looking for a refresher on core principles.
From leading experts in fracture mechanics, this new text provides new approaches and new applications to advance the understanding of crack initiation and propagation.
