Conclusions
Two difficulties arise when modeling structural behavior: one is the need to test accurate models, the other is the use of scaling laws. Having solved the first, direct scaling from model to full-size structure is still only possible when both fail in the same manner. This restricts the value of the experiment, which should be combined with the mathematical analysis. Geometric imperfections, compatible with the manufacturing tolerances, can be modeled, but not residual stresses, which may have an important effect on the strength of the structure. It is clear that the best use of the method described is in providing physical models of complex shell structures for checking experimentally the validity of mathematical models.
