10. Fracture mechanics
10.1 Fault propagation
Another approach to analyzing the fatigue behavior of constructional details – is "timidly" envisaged by NF EN 1993-1-10 – and consists in making use of the rules of fracture mechanics, whose use in current practice remains limited.
Stresses, strains and displacements are proportional to a single parameter: the stress intensity coefficient, . This parameter depends on the loading of the cracked detail and the geometries of the detail and defect.
The fault does not propagate when remains below a critical value,...
