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