Piezoelectricity above the Curie temperature? Combining flexoelectricity and functional grading to enable high-temperature elect

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.

Simulation-based numerical optimization of arc welding process for reduced distortion in welded structures

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

PhD Studentship in Computational Mechanics of Porous Metallic Materials

We are offering the PhD studentship at the
University of Surrey, and we are looking for enthusiastic and self-motivated candidates.

This project focuses on applications of metallic foams where structural functionality is combined with energy absorption, damping, heat insulation, and noise silencing.

Postdoctoral Position Available at University of Western Ontario, Canada

Position is available for a postdoctoral fellow to carry out an industry sponsored project on carbon fiber composite modeling. The contract is initiated for one year, with possible extension if work progresses satisfactorily. The research will focus on

 (1)  micromechanics modeling of elastic and viscoplastic behavior of injection molded carbon fiber composites;


 (2)  homogenization techniques and constitutive model development for vibration, strength and impact simulations of carbon fiber composites.
