Fatigue Prediction for Random Loads

Fatigue Prediction for Random Loads serves as a comprehensive treatise for methods for fatigue estimation and fatigue life prediction in randomly excited structural systems using the rainflow cycle counting method.

Fatigue is an important mode of material degradation in structural components subjected to vibrations and a reliable estimation of their fatigue life span, and it is a key consideration in the design and development of such systems. This book uses advanced concepts of probability theory, random variables and random processes to develop spectral-based methods and formulae for predicting expected fatigue damage and expected fatigue life. The developments presented here bypass the need for a computationally expensive rainflow cycle counting that is usually adopted in time domain approaches.

This book is aimed towards researchers and industry practitioners working in the intersectional areas of mechanics and applied mathematics and is expected to be particularly useful for applications on problems in the fields of wind engineering, offshore engineering, ship research and routing, aerospace engineering, automotive engineering and machine dynamics.

Igor Rychlik is Professor Emeritus at Chalmers University of Technology, Sweden. He earned a PhD in mathematical statistics at Lund University, Sweden, 1986. During 1988–1990 he was a post-doctoral student at the Department of Statistics, Colorado State University, and in 1995 he was a visiting professor at the University of Queensland, Brisbane, Australia.

Georg Lindgren is Professor Emeritus in the Engineering Faculty at Lund University, Sweden. He earned a PhD in mathematical statistics at Lund in 1972 with a thesis inspired by an intriguing question regarding random load cycle ranges. After a period as an Associate Professor at Lund and Umeå, he became a Professor of Mathematical Statistics at Lund in 1986, and since 2006 he has been a Professor Emeritus. His main interest is random processes and their use in communication technology, marine and mechanical engineering and medicine. He is a coauthor of a 1983 research volume on the extremes and related properties of random sequences and processes and two research/advanced student texts on stationary stochastic processes. He is a member of the Royal Swedish Academy of Engineering Sciences (IVA).
