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.

Hi,

I have to use Hamilton pricinple to evaluate the diff. equation of motion of a string. As shown in the figure below, the string is hanged from one end and is free at the other. The flexural stiffness of the string is negligible.

I have a problem with the potential energy of the string! required in the Hamilton principle. Since the flexural stiffness of the string is assumed to be negligible, is there any other term for potential energy? 

Hallo every body,

who knows about Extended kantorovich method?

The University of Michigan (UM) and Shanghai Jiao Tong University (SJTU) have established a Joint Institute (JI) in Shanghai with a commitment to build a world-class academic research and educational institution. The UM-SJTU Joint Institute invites applications for tenure-track (Assistant, Associate, and Full Professor) positions in all emerging fields of engineering with emphasis on mechanical and electrical/computer engineering. These positions are open to top caliber applicants from around the world. With its unique academic mission in China and connection to SJTU's established research, the JI offers faculty extraordinary opportunities to develop major research programs.

Hi everyone,
 
 I'm searching some solution to absorb vibration. I'm trying to find materials and their properties to compare between them and chose one to design a vibration damper. Their application will be on the base of an avionics enclosure wich is onboard of a UAV (Unmanned Aerial Vehicle).

I'm the university, I learned mx''+cx'+kx=0, the free vibration equilibrium equation and all that stuff. But how should I search for a material wich have a good 'c'? Should I search for viscoelastic materials? I eared that ruber or cork are very good vibration absorbers, but how to quantify and compare it?

I would aprecciate some help... thanks in advance
Best regards
Sonia PireX

The JI has been given a high degree of autonomy to model itself on world-class US universities. The students are among China’s best.

Can anybody suggets, (especially working in experimental field on CNTs ) whether there is any change in vibrational characteristics in CNTs subjected to temperature change.(especially in fundamnetal frequency values)
