A high-efficiency circular vibration/polarization ultrasonic conversion technology capable of detecting cracks, which can occur in various directions within a structure, has been developed for the ...

Recent advances in the study of acoustic radiation and vibrational analysis of circular plates have significantly deepened our understanding of how structural motions generate sound. This field ...

The last few years have shown progress in finite-element analysis intended for use by design engineers. Many programs that work with CAD provide several different types of analysis, and the range of ...
