Description
This book describes integrity management procedures for thin-walled structures such as gas pipelines including various methods for analysis of crack growth in thin-walled structures and probability of failure evaluation of pipelines using Monte-Carlo simulation. The focus of this book is the practical applications of boundary element method, finite element method and probabilistic fracture mechanics. Popular methods for SIF calculation, crack growth are presented in the book. The evaluation of failure probabilities based on BS7910 is explained in detail. The procedures described in the book can be used to optimise the maintenance of pipelines and thereby reducing the cost of operating such pipelines. This book will be of interest to pipeline engineers, postgraduate students and university researchers.
