Book Description
and Literature Rev iew Chapter 1 1. INTRODUCTION AND LITERATURE REVIEW The exploration for oil and gas in ever increasing water depths has given an impetus to research efforts on the behaviour of offshore structures under ocean environment. These structures are continuously subjected to environmental loading because of waves, wind and current. A response analysis is required to assess the safety of offshore structure under severe storm conditions as well as for estimation of damage caused by less severe but more frequently occuring sea states. A majority of the reported failures in the life time of offshore structures are in fact fatigue failures. The offshore structures are usually built in the form of welded tubular structures. The joints of these tubular members experience the fatigue damage mainly due to small defects in welding which act as crack initiators, high stress concentrations and the variable loads. The variable loads due to the ocean waves cause cyclic stress variation in the structural members and the accumu lated effect of these stresses results in the fatigue failure.

Book Description
This volume contains the results of the third phase (1981 - 1987) of a research programme on the in-service behaviour of welded marine structures under fatigue and corrosion fatigue loading. The programme was undertaken in six EEC countries (Denmark, France, Germany, Italy, The Netherlands, United Kingdom) in close association with similar work being undertaken in Norway and Canada. In all, more than 40 research laboratories have been involved in an overall collaboration aimed at generating information relevant to the performance of offshore steel structures and fostering a precise degree of common technical understanding that will encourage the increased use of structural steel fabrications for the exploitation of offshore hydrocarbon reserves throughout the world. The programme has already produced tangible benefits for both the steel and oil industries through the contribution it has made to a better understanding of the behaviour of steel structures in marine environments as well as by providing the data necessary for the revision of codes of practice relating to the fabrication of these structures.

Book Description
Full-scale Fatigue Testing of Components and Structures presents the approaches to the testing of full-scale components or structures. The book begins by examining the necessity or desirability of full-scale fatigue testing. Subsequent chapters are devoted to the discussion of fatigue testing done on aircraft structures, railway components, helicopter rotor heads, artillery gun structures, and bridge components. The role of full-scale fatigue testing on automotive components and systems, structural testing in nuclear engineering, and the use of a structural fatigue testing laboratory for other tests are covered as well. Engineers, materials scientists, and researchers in the field of fatigue testing will find the book very useful.

Book Description
This book provides practicing engineers, researchers, and students with a working knowledge of the fatigue design process and models under multiaxial states of stress and strain. Readers are introduced to the important considerations of multiaxial fatigue that differentiate it from uniaxial fatigue.

Book Description
The purpose of this Handbook is to provide a review of the knowledge and experiences in the field of fatigue fracture mechanics. It is well-known that engineering structures can fail due to cyclic loading. For instance, a cyclically time-varying loading reduces the structure strength and can provoke a fatigue failure consisting of three stages: (a) crack initiation (b) crack propagation and (c) catastrophic failure. Since last century many scientists have tried to understand the reasons for the above-mentioned failures and how to prevent them. This Handbook contains valuable contributions from leading experts within the international scientific community and covers many of the important problems associated with the fatigue phenomena in civil, mechanical and nuclear engineering.

Book Description
Offshore Engineering continues to develop and expand rapidly. While in the public eye its focus has shifted towards subsea and floating developments in ever deeper waters, bottom founded structures are still at the industry’s heart. The fixed structure remains its dependable workhorse and even today newly installed fixed structures far outnumber subsea and floating applications. Additionally, the knowledge and technology that have (literally) pushed the boundaries of Offshore Engineering into ever more demanding environments and water depths have been largely pioneered by bottom founded structures. An engineer’s central skill is to develop coherent and balanced models for the problems encountered. Regrettably, due to availability of ever more sophisticated computer applications this expertise is at risk of getting lost, and adopting computer outcomes without truly understanding the models and their limitations is naive, risky and unprofessional. Therefore, every engineer needs fundamental knowledge and understanding of underlying theories and technologies. This Handbook is intended to help offshore engineers acquire and sustain relevant expertise in some notoriously difficult subjects. It attempts to stimulate reflection and critical evaluation of the models used and the strengths and weaknesses of the solutions found. While dealing more specifically with bottom founded structures, the material is generally applicable to offshore structures of all types. The Handbook can be used as a textbook for Master’s students and as a manual and reference guide for practising professionals.
