Abstract: Use of structural models made of materials different from full-scale offers promise of allowing considerable latitude in choice and model test conditions, particularly in the intensity and duration of loading. An analytical and experimental evaluation of the feasibilty and potential of this approach has therefore been made. Presented are an analysis of the general similitude requirements for the modeling of dynamic responase of aerospace structures utilizing dissimilar materials and an investigation of the problems associated with meeting these requirements. Also, test models involving the elastic-plastic response of impulsively loaded beams and plates made of relatively weak and dense lead-loaded plastic are described and their results are compared with independent full-scale results for aluminum. Agreement indicates probable usefulness of approach.
