Material Detail

Elastic waves in the active (ultrasound) and passive form (acoustic emission) provide an ideal approach for the non-destructive inspection of materials. They are used for all types of materials and structures, having many advantages over other traditional measurements. Although they are already applied in a usual basis in the structural health monitoring of structures, new challenges arise. These are related to pushing the limit of the characterization capacity further: detecting smaller cracks, providing more information on the condition of the material, predicting the useful life time, and characterizing new innovative materials that have not been tested before.

The articles contained in this issue/book include a broad range of materials from masonry and concrete to ceramics, composites, 3D printed metals and medical prosthetics and structures from cultural heritage towers and concrete beams to marine and aeronautic structures and solar panels. Characterization concerns the fracture mode, remaining fatigue life, disbonds in bonded stiffeners, localization of defects, condition of injection molding tools and many others.
