I'm currently working on modeling 3 phases composites material. However, I'm having hard time on finding the transverse modulus as it's different from analytical results. I've been using Mori-Tanaka approach to determine the stiffness moduli. Does anyone know how to obtain a correct values for the transverse moduli? 

The Piezoelectric Device Laboratory has immediate opennings for recent PhDs.  We are engaged in researchs in piezoeelctric acoustic wave resonators with supports from government and indsutry.  The Laboratory has been grwoing and we would like to have new members to accelerate the pace and expand collaborations with the fast growing piezoelectric acoustic wave device industry in China and other countries.

We are looking for new PhDs with background in Solid Mechanics with experiences on theoretical and experimental work in acoustic waves, computational mechanics, piezoelectric materials, sensors, acutators, resonators, and applications.

ADINA offers a comprehensive array of multiphysics capabilities tightly integrated in one program:

* Fluid-structure interaction (FSI)
* Thermo-mechanical coupling (TMC)
* Structural-pore pressure coupling (porous media)
* Thermal-fluid-structural coupling
* Electric field-structural coupling (piezoelectric)
* Thermal-electrical coupling (Joule heating)
* Acoustic fluid-structural coupling
* Fluid flow-mass transfer coupling

For 31 mode piezoelectric plate. I have measured it's electric impedance spectrum (curve of Log IZI~ Frequency). I found that, when I used this plate for a piezoelectric sensor to receive mechanic signals. the maximum output  occured at antiresonance frequency;   For example, for piezoelectric hydrophone or receiving-type piezoelectric transducers, It works at antiresonance frequency (at the maximum electric impedance). 

Advances in the research of the theory of Piezoelectricity and Acoustic Waves have provided essential foundation and new opportunities to device technology and have been fostering academic exchanges and interaction in the piezoelectric device industry.With the increased research activities in piezoelectricity and acoustic waves and recent fast growth in piezoelectric devices, we are also facing many technological challenges from real engineering applications and product design and manufacturing.Following the successful SPAWDA 2004 in Ningbo, Chinese Society of Theoretical and Applied Mechanics, IEEE UFFC and the Acoustical Society of China have decided, also with industrial support, to hold the SPAWDA 2006 at Zhejiang University, Hangzhou, Zhejiang, China from December 14-17.The conference topics include, but not limited to,
