A fast Fourier transform (FFT) based computational approach integrating phase-field method (PFM) and crystal plasticity (CP) is proposed to model recrystallization of plastically deformedâ€¦ (More)

We investigate the Cerium â€“ isostructural phase transition by explicitly incorporating finite temperature mixing of the Ce nonmagnetic and magnetic states. Unique to our approach is the calculationâ€¦ (More)

We propose a mixed-space approach using the accurate force constants calculated by the direct approach in real space and the dipole-dipole interactions calculated by linear response theory inâ€¦ (More)

The stability and evolution of ferroelectric domain structures in thin films are studied. Elastic solutions are derived for both elastically anisotropic and isotropic thin films with arbitrary domainâ€¦ (More)
