The engineering problem of the presented research project is based on the design and loading of the aerospace structure shown in Figure 15.1. Although the example in Figure 15.1 depicts a possible structure of a hypersonic vehicle, the construction is typical for supersonic and common subsonic transport aircrafts. To examine the basic phenomena of the load‐carrying behaviour in the postbuckling range, the analysis of such structures can be reduced to a simplified mechanical model of an initially flat, shear‐loaded panel. For practical reasons, our investigations were limited to aluminium (Al2024‐T3) panels at ambient temperature and 200 °C. Within the high postbuckling regime or at high load levels and elevated temperatures in supersonic vehicles, moderate inelastic strains occur and the behaviour of the considered structure becomes geometric and physically non‐linear.
