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.

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.
A postdoctoral research associate opening with a primary focus on atomistic simulations of defects and mechanical behaviors of Mg and Mg alloys is available in Liang Qi’s group (http://cms.engin.umich.edu/) at University of Michigan, Ann Arbor. Qi’s group is involved in the PRedictive Integrated Structural Materials Science Center (PRISMS), a DOE-BES funded research center dedicated to integrated computational and experimental studies of structural alloys located at University of Michigan.
Link to our new paper outlining some strategies to steer interfacial debonding to a desired interface during a demolding process when the two interfaces in a 3-layer structure are equally weak. The article can be downloaded for free until July 5th. Would sincerely appreciate any feedback.
