Modeling the Locomotion of Soft Robots using Discrete Elastic Rods
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:
Nanoscale self-healing mechanisms in shape memory ceramics
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.
Competition between formation of Al2O3 and Cr2O3 in oxidation of Al0.3CoCrCuFeNi high entropy alloy: A first-principles study
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.
Postdoc position in atomistic simulations of grain boundaries in Mg alloys at UMich
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.
Preferential debonding during demolding of a sandwiched elastomeric layer
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.
