A simple model for some unusual properties of martensitic transformation
S. Sreekala, Rajeev Ahluwalia, G. Ananthakrishna
We report a detailed numerical investigation of a recently introduced two dimensional model for square-to-rectangle martensitic transformation that explains several unusual feature…

Landau Theory For Shape Memory Polycrystals
Rajeev Ahluwalia, Turab Lookman, Avadh Saxena +1
We propose a Ginzburg-Landau theory for the elastic properties of shape memory polycrystals. A single crystal elastic free energy for a system that undergoes a square-to-rectangle…

Electromechanical Properties of Multi-Domain Ferroelectrics
Rajeev Ahluwalia, Turab Lookman, Avadh Saxena +1
We study theoretically the influence of the underlying domain microstructure on the electromechanical properties of ferroelectrics. Our calculations are based on a continuum approa…
