The University of Tulsa Department of Mechanical Engineering is searching for a postdoctoral researcher to support our recently awarded a U.S. Department of Energy Solar Energy Technology project to develop novel a CSP Collector system https://www.energy.gov/eere/solar/seto-fy2018-concentrating-solar-therm… TU and collaborators will develop a new carbon-based receiver system with a bio-inspired microvascular architecture.
Enthusiastic and highly motivated postdoctoral scientists are sought to work with Dr. Kun Zhou at the School of Mechanical and Aerospace Engineering, Nanyang Technological University, Singapore on the following areas:
1. Metal printing and process modeling (DED or SLM printing)
2. Polymer printing (polymer synthesis, modification and MJF/SLS printing)
We have an open PhD position starting in the Spring or Fall semester 2020 at the Computational Laboratory for the Mechanics of Interfaces at the University of Tennessee – Knoxville. A high quality PhD student is sought to study failure of structural materials under fatigue by developing a novel computational approach that explicitly targets traction equilibrium and displacement compatibility along the grain boundaries.

How does geometric non linearity handled in Explicit Simulations ?
Dear Colleague,
I write to bring your attention to a recent paper describing the use of a planar version of Bergou et al.'s discrete elastic rod theory to model and simulate a prototype caterpillar-inspired soft robot. The paper just appeared in Soft Robotics:
Shape memory ceramics, such as yttria-stabilized tetragonal zirconia (YSTZ), offer unique properties including ultra-high operating temperatures and high resistance to oxidation. However, they are susceptible to formation of defects during manufacturing and/or by mechanical deformation. To completely take advantage of their shape memory properties, it is necessary to fully understand the nano-structural evolution of defects under external stimuli. In this study, defect evolution behaviors in YSTZ nanopillars are investigated by atomistic simulations.
We studied the oxidation behavior of face-centered cubic Al0.3CoCrCuFeNi high entropy alloy through first-principles calculations. Three surface orientations were chosen for oxidation, and all the possible combinations of atomic positions at these surfaces were considered. The adsorption energy of oxygen adhesion to the studied surfaces was the lowest for the sites with more neighboring Cr atoms, and the second most favorite site for oxygen adsorption had more neighboring Al atoms.
