- Data about the structure reliability in the concept stage of design and in operation,
have to be included when prescribing for a procedure designing against fracture.
Unified procedure for designing against structural fractures, based on principles of
safe use of structures and presented in Fig. 1, is accepted in the framework of the
FITNET project /11/, funding by EC.
Figure 1: Procedure for design against failure of a structure
Figure 1 shows all steps in the procedure for designing against structural fracture. The
application of this procedure starts at the structure design stage, and it should be applied
during manufacturing and service until the final usage. The final stop of structure usage is
determined by increased risk of failure, for a value higher than the reliable safety factor.
