The purpose of Fitness-for-Service Fracture Assessment of Structures Containing Cracks is to facilitate the use of fracture mechanics based failure assessment procedures for the evaluation and design of structures and components. All practical structures contain flaws and the optimum combination of cost efficiency and safety whilst achieving the required capability, can only be realised by using state of the art methods such as that represented by the European flaw assessment method SINTAP/FITNET to analyse the safety risk. This book is written by practitioners with extensive experience in both the development and use of integrity assessment methods and provides comprehensive information on the basic principles and use of analytical flaw assessment. It provides an introduction to the method, its background, how it can be applied, its potential and, importantly, its limitations. The explanations are complimented by using a large number of worked examples and validation exercises which illustrate all aspects of the procedure. In addition, for students and engineers who are new to the subject, a comprehensive glossary of basic terms used in fracture mechanics based integrity evaluations is included.

The topics addressed include:

Crack driving force and failure assessment diagram type analyses Preparation of the input parameters Determination of the model parameters, Treatment of combined primary and secondary loading, together with residual stress effects Analysis of the effect of constraint effects Treatment of mixed mode loading Consideration of the influences of strength mismatch Reliability aspects
