This International Standard is intended to be used for the determination of the stress/strain distribution and
margins of safety in launch vehicles and spacecraft primary structure design. Liquid propellant engine
structures, solid propellant engine nozzles and the solid propellant itself are not covered, but liquid propellant
tanks, pressure vessels and solid propellant cases are within the scope of this International Standard.
This International Standard provides requirements for the determination of maximum stress and
corresponding margin of safety under loading, and defines criteria for static strength failure modes, such as
rupture, collapse and detrimental yielding. Critical conditions associated with fatigue, creep and crack growths
are not covered. Notwithstanding these limitations in scope, the results of stress calculations based on the
requirements of this International Standard are applicable to other critical condition analyses.
In accordance with the requirements of this International Standard, models, methods and procedures for
stress determination can also be applied to the displacements and deformation calculations, as well as to the
loads definition, applied to substructures and structural members of structures under consideration. When this
International Standard is applied, it is assumed that temperature distribution has been determined and is used
as input data.
