RA position is available in the University of Alabama in Huntsville

Submitted by eunseoklee on

One immediate graduate student RA position is available. The potential student will register to the department of mechanical and aerospace engineering and perform graduate research in the area of energy storage/conversion using first-principles calculations. Stipend and tuition support will be provided.

Any student who has a background in physics and/or materials science at either atomic scales or continuum scales is welcomed to email his/her CV to Prof. Eunseok Lee (eunseok.lee [at] uah.edu).

Multiscale real-space quantum-mechanical tight-binding calculations of electronic structure in crystals with defects using perfectly matched layers

Submitted by pourmatin on

<p>We consider the scattering of incident plane-wave electrons from a defect in a crystal modeled by the time-harmonic Schrödinger equation. While the defect potential is localized, the far-field potential is periodic, unlike standard free-space scattering problems. Previous work on the Schrödinger equation has been almost entirely in free-space conditions; a few works on crystals have been in one-dimension. We construct absorbing boundary conditions for this problem using perfectly matched layers in a tight-binding formulation.

Question about Anisotropic Plasticity models (Hill48)

Submitted by Aleksander Marek on

Dear all,

Recently, I've started working on developing effective algorithm for extracting constitutive parameters from full-field measurements for anisotropy plasticity. Our first reference model was chosen as Hill48 due to relatively simple form, popularity etc. Since we are new to that topic we had discussion with my supervisor about nature of anisotropic plasticity and here are some crucial points.
