Most technologically relevant ferroelectrics typically lose piezoelectricity above the Curie temperature. This limits their use to relatively low temperatures. In this Letter, exploiting a combination of flexoelectricity and simple functional grading, we propose a strategy for high-temperature electromechanical coupling in a standard thin film configuration.
The School of Mechanical Engineering and Mechanics, Ningbo University, is looking for cadidates for all subjects in the broad field of mechanical engineering and mechanics. In addition to traditional field of impact and shock waves, piezoelectric devices, material durability, and metal forming, the school are also initiating new directions like vechicle engineering, fluid mechanics, occean engineering, solid mechanics, thermodynamics, vibrations, strength, and other related subjects.

hello Dear friends
I am working on geometrically nonlinear behavior of 2D beam.
I used field consistent approach using total lagrangian. because of field consistency, satisfication tangent stiffness matrix is dependent to tangant of node angles. this means that when beam is subjected to pure bending when angle of rotation approches to 90 degree, tangent stiffness matrice become singular. can any one give solution to this problem. how about corotational formulation.
thanks a lot.
best regards.
Hi,
Can any one know the way to give and impact force in ANSYS workbench static structural ?
Thanks
