The University at Buffalo (SUNY) seeks a tenure-track assistant professor in the broad area of multiscale modeling of the production, assembly, and properties of engineered nanoscale materials, structures, or devices. Appointment at higher rank is possible in exceptional cases. For the details, please check the attachment.

We know from fracture mechanics theories that fracture instability in a perfectly brittle material occurs when energy release rate (G) becomes equal or more than two times the surface energy (γ) of that material. The value of G = 2γ is known as fracture toughness Gc. This is the classical Griffith criteria of brittle fracture. Experimentally, however, we know that plasticity becomes eminent for most materials and this criteria does not work.
I would like to know whether any works have been done in EFGM which suggest the best points in the domain where the stresses have to be computed, like in FEM we do have Gauss points which give minimum error for secondary variables. So can any one please suggest some references in this regard?
The notes on finite deformation have been divided into two parts: special cases and general theory (node/538). In class I start with special cases, and then sketch the general theory. But the two parts can be read in any order.
Hi Friends
I want to share some of our recent research work on the stress induced phase transformation of CuZr nanowire which is published in Materials Letters.

Classical plasticity models evolve state variables in a spatially independent manner through (local) ordinary differen-
tial equations, such as in the update of the rotation field in crystal plasticity. A continuity condition is derived for the
lattice rotation field from a conservation law for Burgers vector content—a consequence of an averaged field theory
of dislocation mechanics. This results in a nonlocal evolution equation for the lattice rotation field. The continuity
