Definitions

The theory of discontinuities and dynamic conditions of compatibility are useful tools for checking for the hyperbolicity of equations describing the dynamic behavior of thin-walled structures.

Backgrounds and Some Historical Remarks

Thin-walled beams of open section are extensively used as structural components in different structures in civil, mechanical, and aeronautical engineering fields. These structures have to resist dynamic loads such as wind, traffic, and earthquake loadings, so that the understanding of the dynamic behavior of the structures becomes increasingly important. Ship hulls also can be modeled as thin-walled girders during investigation of hydroelastic response of large container ships in waves (Senjanović et al., 2009).

The classical engineering theory of thin-walled uniform straight and horizontally curved beams of open cross section was...
