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.

This year we are again organising the Computational Biomechanics for Medicine (CBM) Workshop (http://school.mech.uwa.edu.au/CBM2014/) together with the Medical Image Computing and Computer Assisted Intervention Conference (MICCAI) (http://www.miccai2014.org/). This year, the workshop will be hosted by Massachusetts Institute of Technology (MIT), Boston, USA, on 14th September 2014.
This paper presents an effective numerical approach for welding process
parameter optimization to minimize weld-induced distortion in
structures. A numerical optimization framework based on coupled Genetic
Algorithm (GA) and Finite Element Analysis (FEA) is developed and
implemented for a low and a high fidelity model. Classical weakly
coupled thermo-mechanical analysis with thermo-elasto-plastic
assumptions is carried out for distortion prediction of numerical
models. The search for optimum process parameters is executed by direct
integration of numerical models and GA-based optimization technique. The
developed framework automatically inserts the process parameters into
the simulation models, executes the FE-based welding simulations and
As a close collaborator and active member of Global Engineering and Materials, Inc (GEM), I would like to present you a research and development position at GEM. The information below can also be found in the attached PDF file.
