The author discusses in detail the fundamentals and recent advances in fatigue analysis
with special emphasis on crack mechanics and fatigue design of structural details. This
title is intended for engineers, research staff, professors and graduates engaged in
fatigue preventing design and survey, fatigue studies of materials and structures,
planning repair and maintenance, and strength standard development.

This monograph presents the state-of-the-art and recent advances, including those by
the author, in fatigue studies. It is designed to be a useful tool in many practical
applications. The fatigue damage of structures is discussed mainly as a two-stage
process consisting of a crack nucleation phase and a sub-critical crack propagation
phase. Crack initiation models are regarded relevant for fatigue design and the crack
propagation models are regarded as the means of fatigue reliability assessment of
structures. Major factors affecting crack initiation and propagation are examined. The
S-N curve and Local Strain formats are used to model the damage process in the
initiation period. By defining the initial crack size, provisional though, the necessary link
between the stages of the process is provided. The crack growth is specified mostly in
terms of linear fracture mechanics, however the unified approaches are suggested
based on the application of cyclic plasticity. The emphasis is put on the effects of stress
concentration, residual welding stresses, and random loading, as well as on statistical
aspects of the damage accumulation and crack growth. Special attention is focused on
the methodologies of the fatigue design of structural details, including the procedures
approved by the classification societies.

The methodologies and information in the book are addressed to engineers, naval
architects, research staff, professors and graduates engaged in fatigue preventing
design and survey of marine structure, in fatigue studies of materials and structures, in
experimental laboratory research, in planning the repair and maintenance of affected
structures, and in rule development including in-service reliability systems, etc. The
book is also an effective educational aid in naval architecture, marine, civil and
mechanical engineering. The author, a professor at St. Petersburg Marine Technical
University and the head of Strength & Reliability Laboratory, Mechanical Engineering
Research Institute, Russian Academy of Sciences, is an internationally recognized
expert leading for decades in experimental and theoretical research in this field.
