Visualizing deformation gradient via SDV in Abaqus VUMAT
Hi everybody,
I have a very basic question. Is it possible to define the deformation gradient as a state variable in VUMAT and visualize it through SDV? If yes can you please suggest how to definr state variable? Thanks in advance!

Faculty position openings at Stony Brook University
The Department of Civil Engineering at Stony Brook University has started a search for 3 tenure-track faculty positions at the assistant professor or associate professor level with a desired start date of September 2020. We seek to fill the positions (one each) in the following areas:
1. Geotechnical Engineering. For this position, we are primarily interested in applicants who have expertise in energy geotechnics and coastal geotechnics. Also of interest is environmental geotechnics.
A variant of Irving-Kirkwood-Noll formulation for one-dimensional nanostructures
We present a one-dimensional variant of the Irving-Kirkwood-Noll procedure to derive microscopic expressions of internal contact force and moment in one-dimensional nanostructures. We show that these expressions must contain both the potential and kinetic parts: just the potential part does not yield meaningful continuum results. We further specialize these expressions for helically repeating one-dimensional nanostructures for their extension, torsion and bending deformation. As the Irving-Kirkwood-Noll procedure does not yield expressions of stiffnesses, we resort to a thermodynamic equilibrium approach to first obtain the Helmholtz free energy of the supercell of helically repeating nanostructures. We then obtain expressions of axial force, twisting moment, bending moment and the associated stiffnesses by taking the first and second derivatives of the Helmholtz free energy with respect to conjugate strain measures. The derived expressions are used in finite temperature molecular dynamics simulation to study extension, torsion and bending of single-walled carbon nanotubes and their buckling.
