The importance of interfaces to the mechanical behavior and failure of advanced materials in service is well established. Therefore, understanding o
the complexity of the interface mechanics and development of methods of
interface characterization are of great significance and interest. The aim of the
symposium on "Ultrasonic Characterization and Mechanics of Interfaces" was
to bring together researchers from the materials science and mechanics communities active in experimental and theoretical work on ultrasonic interface
characterization and interface mechanics.
This volume is a collection of twenty original articles from twenty-eight invited papers presented at the symposium. For the reader's convenience, the
papers are organized into four topical sessions:
- Microstructural Aspects of Interfacial Fracture
Mechanics of Interfacial Fracture
- Ultrasonic Characterization of Layered Interfaces
- Ultrasonic Characterization of Cracked Interfaces
Within each section the papers are arranged in alphabetical order by the
first author's last name.
In the first section, material aspects of interfacial fracture are addressed. The
effect of microstructure on interfacial failure in bimaterials and composites is
considered, together with mechanical and acoustic emission methods for
characterization of microstructural effects on fracture. The second section ad-
dresses the linear and nonlinear aspects of interfacial fracture, dynamic effects
of crack propagation, and isotropic and anisotropic bimaterial interfacial failure. The third section is devoted to ultrasonic characterization of layered interfaces in bimaterials and composites. Both theoretical and experimental
aspects of the latest efforts in this area are reported. In the fourth section
ultrasonic wave scattering from cracked interfaces is considered, relating micromechanical aspects of interface damage to techniques for its ultrasonic
characterization.
The symposium was sponsored by the Applied Mechanics Division of the
ASME and organized under the auspices of the Wave Propagation and Composite Materials Committees. The editors express their gratitude to the authors
for their excellent contributions.
