This paper presents development of allowable stress estimation methods specifically tailored to preliminary design weight prediction. The paper presents a unique analytical technique for projecting test results to cover a large variety of material/temperature combinations, including composite materials. It is shown how this approach overcomes inaccuracies and limitations associated with stress ratioing techniques by providing accountability for material strength limitations such as plasticity. Methods for compression, tension/fatigue and shear are developed. Discussions are limited to primary wing, tail and body structure. Method application examples are included in the paper.
