TALAT Lecture 2401: Fatigue Behaviour and Analysis

Description

This lecture explains why, when and where fatigue problems may arise and the special significance to aluminium as structural material; it helps to understand the effects of material and loading parameters on fatigue; to appreciate the statistical nature of fatigue and its importance in data analysis, evaluation and use; it shows how to estimate fatigue life under service conditions of time-dependent, variable amplitude loading; how to estimate stresses acting in notches and welds with conceptual approaches other than nominal stress; it provides qualitative and quantitative information on the classification of welded details and allow for more sophisticated design procedures. Background in materials engineering, design and fatigue is required.

3.35 Fracture and Fatigue (MIT)

Description

Investigation of linear elastic and elastic-plastic fracture mechanics. Topics include microstructural effects on fracture in metals, ceramics, polymers, thin films, biological materials and composites, toughening mechanisms, crack growth resistance and creep fracture. Also covered: interface fracture mechanics, fatigue damage and dislocation substructures in single crystals, stress- and strain-life approach to fatigue, fatigue crack growth models and mechanisms, variable amplitude fatigue, corrosion fatigue and case studies of fracture and fatigue in structural, bioimplant, and microelectronic components.

TALAT Lecture 2402: Design Recommendations for fatigue loaded structures

Description

This lecture presents calculation of design stresses for variable stress ratios in practice, explanation on the background of design recommendations; it demonstrates the concept of partial safety factors and supply appropriate background information for aluminium; it enables the designer to evaluate service behavior of structural details on a more sophisticated level applying the same principles as in current design recommendations; it provides understanding of the fatigue design procedure according to current recommendations. Background knowledge in engineering, materials and fatigue as well as some knowledge in statistics is required.

TALAT Lecture 2405: Fatigue an Fracture in Aluminium Structures

Description

This lecture outlines modern fatigue design procedures and standards, the respective background information; it introduces fatigue design by testing; it presents fatigue data analysis and evaluation; it covers safety and reliability issues in aluminium design. This material has been utilized together with further definitions for classification of structural details to provide a proposal supported by the European Aluminium Association as a National Application Document, which may also be considered for introduction into the actual standard when this will be converted from an ENV to an EN.
