FATIGUE OF WELDED METAL ENGINEERING STRUCTURES. INTRODUCTORY REPORT TO A RESEARCH PROGRAMME

FATIGUE DES OUVRAGES D'ART METALLIQUES SOUDES - RAPPORT INTRODUCTIF A UN PROGRAMME DE RECHERCHE

The first chapter of this bibliographic study presents the general aspects of the problem of fatigue in welded metal structures. Chapter 2 recalls the mathematical or physical damage theories, while notions of life time and strength of members subjected to fatigue are defined together with fatigue test principles and procedures. Test results are utilized according to probabilistic statistical methods which can be expressed in analytical mathematical laws, if simplifying assumptions are accepted. Chapter 3 describes the parts of a metal structure under traffic, which are most exposed to risks of damage due to fatigue. Chapter 4 studies the influence of the characteristics of welded joints on the fatigue behaviour of couplings. These characteristics are either of geometric origin, including porous spots, blisters and defects due to lack of fusion or of metallurgical origin. Means of improving the fatigue behaviour of welded joints are outlined. In conclusion remarks are made on the representativeness of tests on samples in a study conducted to forecast the fatigue behaviour of a structure. /TRRL/
