Abstract
This work shows the wave propagation in fluid-solid interfaces due to dynamic excitations, such interface waves are known as Scholtes waves. We studied a wide range of elastic solid materials used in engineering. The interface connects an acoustic medium (fluid) and another solid. It has been shown that by means of an analysis of diffracted waves in a fluid, it is possible to deduce the mechanical characteristics of the solid medium, specifically, its propagation velocities. For this purpose, the diffracted field of pressures and displacements, due to an initial pressure in the fluid, are expressed using boundary integral representations, which satisfy the equation of motion. The initial pressure in the fluid is represented by a Hankels function of second kind and zero order. The solution to this problem of wave propagation is obtained by means of the Indirect Boundary Element Method, which is equivalent to the well-known Somiglianas representation theorem. The validation of the results was performed by means of the Discrete Wave Number Method. Firstly, spectra of pressures to illustrate the behavior of the fluid for each solid material considered are included, then, the Fast Fourier Transform algorithm to display the results in the time domain is applied, where the emergence of Scholtes waves and the amount of energy that they carry are highlighted.

Service life prediction of engineering materials even during virtual design period is of great interest
for engineers and materials designers. Within different industrial fields of application from
construction engineering to automotive and aviation various aggressive exposure cases can occur.
Related corrosion issues lead to unwanted and time consuming measures and expensive maintenance
action. Thus, minimization of this action during virtual design via corrosion related predictive
modelling would be a tremendous tool.
The realization of such action requires a conceptual framework. Based on existing work the talk will
discuss recent progress within this field, present some of the latest corrosion modelling activities and
point out most challenging issues like scale linking, interoperability or validation. Demands in
prospective corrosion related modelling research will be discussed.
