Numerical study of the spectral 3-D Green's function singularities for piezoelectric SAW components
(2005)
This article deals with the numerical study of the singularities appearing in the spectral 3-D Green's function associated with the piezoelectric surface acoustic wave components (so-called SAW components). These electrical ...

In-Dressing Acoustic Map by Low-Cost Piezoelectric Transducer
(Ieee-inst Electrical Electronics Engineers Inc, 2020-08-01)
The main difficulty in the grinding process is to identify the correct moment to dress the grinding wheel. Therefore, the cutting tool (grinding wheel) must be monitored. In this context, an innovative technique was developed ...
Detection of cracks in scratching tests in ceramic materials through acoustic emission
