Principles of Fracture Mechanics - Tapa blanda

For a first course in the Mechanics of Fracture at the graduate level (or senior undergraduates with a background in engineering mechanics). The attention of Principles of Fracture Mechanics is on the mathematical principles of linear elastic fracture mechanics and their application to engineering design. The book is a self-contained manual on the mechanics aspects of the theory of brittle fracture and fatigue and is suitable for either self-study or classroom instruction. It includes a guided introduction to the linear theory of elasticity with pivotal results for the circular hole, the elliptical hole and the wedge leading up to the general problem of bodies containing cracks.

Intended for a first course in the mechanics of fracture at the graduate level (or senior undergraduates with a background in engineering mechanics) the focus of the book is on the mathematical principles of linear elastic fracture mechanics and their application to engineering design. The material is presented in a conversational, yet rigorous, manner with the focus on the general formulation of the theory. In this way the origins and limitations of the simplified results presented in other introductory texts is apparent. The selection of topics and order of presentation in the book evolved from a graduate course in fracture mechanics developed by the author over the last two decades.

Key Features of the Book

• Unified mathematical treatment based on the generalized Westergaard formulation provides a coherent basis for the analytical, numerical, and experimental treatment of crack problems in two dimensions.
• Introductory chapter on the linear theory of elasticity with pivotal results for the circular hole, elliptical hole, and the wedge leading up to the general problem of bodies with cracks.
• Thorough treatment of fatigue crack growth behavior including both analytical methods and introductions to the NASGRO 3.0 and AFGROW 4.0 computer programs for lifetime prediction analysis using complex empirical fatigue crack growth models.
• Extensive tables of fracture properties for a wide variety of metallic materials in both English and S.I. units derived from the NASA database.
• Broad spectrum of exercises at the end of each chapter ranging from basic analytic derivations to parametric numerical analysis. Also included is a selection of comprehensive open-ended design problems suitable for capstone project assignments or take-home examinations.
