Summary

The object of this study was to determine whether there are significant size effects in compressive strength of large Z-stiffened sheet stringer panels as compared with geometrically similar smaller models and thus to ascertain whether the prediction of the strength of large panels by model tests is reliable.
The specimens for the study were manufactured from 7075-T6 aluminum alloy. There were four representative types of panel designs, with full-scale and one-quarter-scale panels of each type.
A comparison of the average failing stresses shows that there is no significant effect due to the panel size.
For the panels tested, which failed by general instability, there was no significant compressive-strength size effect between the large Z-stiffened prototype and geometrically similar model panels.
