Annotation -

The course provides an overview of acoustic methods for characterizing the structural and mechanical properties of materials. It focuses on four main areas: acoustic microscopy, ultrasonic testing, internal friction measurement, and acoustic emission. Alongside physical principles and experimental setups, emphasis is placed on data interpretation. Numerous practical examples demonstrate the direct link between acoustic outputs and material microstructure, including its dynamic evolution during in-situ measurements.

Syllabus -

• Introduction to acoustic methods and physical principles (propagation of elastic waves in solids, wave types – longitudinal, transverse/shear, surface waves, interaction of acoustic waves with materials).

• Acoustic microscopy (working principles, applications of acoustic microscopy in the study of surfaces, thin films, interfaces, and the localization of hidden microcracks).

• Ultrasonic testing and non-destructive testing – principles, detection, and quantification of macroscopic defects (pores, shrinkage cavities, inclusions, delamination in composites).

• Internal friction / internal damping (anelatic behavior of materials, physical interpretation of internal friction – interaction of point defects, dislocation motion, and phase transformations).

• Acoustic emission (AE) (physical principles of AE generation, AE sources in materials, AE measurement and analysis, correlation of AE parameters with deformation curves, and interpretation of results with respect to material microstructure).
