11. Summary of the new findings of the thesis

- Explicit secular equations of (Rayleigh, Stoneley, Scholte, Lamb) waves for incompressible anisotropic solids.

- The H/V ratio of Rayleigh waves in layered incompressible orthotropic half-spaces and the incompressible limit method.

- The H/V ratio of Stoneley waves with spring contact.

12. Practical applicability, if any:

Incompressible anisotropic materials are widely used in modern technology. Therefore, the evaluation of the mechanical properties of the incompressible anisotropic structures before and during use is very necessary and meaningful. Explicit secular equations and the H/V ratio are convenient tools for this task.

13. Further research directions, if any:

- Rayleigh waves in incompressible monoclinic materials with the symmetry plane  x1=0 or monoclinic x2=0.

- Stoneley waves in incompressible monoclinic materials with the symmetry plane  x1=0 or x2=0.

- Lamb waves in micropholar, incompressible monoclinic materials with the symmetry plane  x3=0.

- Development of an incompressible limit method for monoclinic materials with the symmetry x1=0 or x2=0 or x3=0.
