Sustained load fracture control is a problem of particular importance for manned spacecraft and orbital stations, owing to the long design lives and limited opportunities for repair. The current ESA approach is based on screening out materials shown to be susceptible to stress corrosion cracking from smooth specimen tests. This approach has worked well for over twenty years, but does not fit into the context of ESA fracture control guidelines. Nor does it consider other types of sustained load fracture. These limitations can be addressed by a comprehensive sustained load fracture control plan. Such a plan is defined and its scope is indicated. Emphasis is given to verification of sustained load fracture control by small scale laboratory testing.
