Individual GaN Nanowires Exhibit Strong Piezoelectricity in 3D 

A RA (MS level) position is available in the Department of Engineering Technology, University of North Texas-Denton in the fields of characterization of piezoelectric crystals, design and modeling of piezoelectric resonators and sensors. The position will start from spring, 2012. Candidates should have a Bachelor/Master's degree in engineering mechanics, mechanical engineering or electrical engineering with good academic standing and should have some experiences in the following:

Hello,

I am trying to model piezoelectric sensors on a concrete beam in ABAQUS. Since I am using brttile cracking model, I have to use ABAQUS / Explicit. But piezoelectric elements are not available in ABAQUS / Explicit.

In some papers I saw that the piezoelectricity modeling problem in ABAQUS / Explicit is solved by replacing it by an equivalent Thermo-Mechanical problem. Does anybody know how to accomplish this?

Do you have any suggestions? Are there any other ways to model piezoelectricity in ABAQUS / Explicit?

Thank you very much,

My research based on the application of piezoelectric materials for power harvesting aspects by using ANSYS simulations in MEMS area.
