Bioinspired hybrid materials from spray-formed ceramic templates, Dwivedi, Flynn, Resnick, Sampath, Gouldstone, Advanced Materials, 2015
Novelty/impact/significance:
Different from most research that explore exquisite fabrications, an industrial thermal spray-based technique is developed for making nacreous brick-and-mortar alumina composites, which allows for controlled architecture across length scales, diverse constituent materials, and easy scaling-up.
A predictive deep-learning approach for homogenization of auxetic kirigami metamaterials with randomly oriented cuts
This paper describes a data-driven approach to predict mechanical properties of auxetic kirigami metamaterials with randomly oriented cuts. The finite element method (FEM)was used to generate datasets, the convolutional neural network (CNN) was introduced to train these data, and an implicit mapping between the input orientations of cuts and the output Young’s modulus and Poisson’s ratio of the kirigami sheets was established. With this input–output relationship in hand, a quick estimation of auxetic behavior of kirigami metamaterials is straightforward.
Architected Elastomer Networks for Optimal Electromechanical Response
Dear Colleagues,
This is the preprint of an article on the design of elastomer networks for optimal electromechanical response that will appear in JMPS. We explore how various structural properties of an elastomer network (e.g. density of cross-links, fraction of loose-end monomers, orientation density of chains, etc.) affects both its bulk elastic and dielectric properties, and its performance as an actuator. (https://doi.org/10.1016/j.jmps.2020.104171).

University of California Merced - Post Doc and Funded Grad Student Openings
My group has openings for post docs and grad students (January start date) who will use reactive molecular dynamics simulations to investigate surface and interface phenomena. Applicants must have a degree (BS/MS for PhD applicants or PhD for post doc applicants) in mechanical engineering, materials science, physics, chemistry or a related field. Please contact Dr. Ashlie Martini at amartini [at] ucmerced.edu for more information.
Postdoc position in design and 3D printing of polymer composites at CU Denver
An immediate postdoctoral position in design and 3D printing of fiber-reinforced polymer composites is available at the University of Colorado Denver. The project aims to develop an integrated workflow of modern composite materials, including optimization design, 3D printing, and application insertion. The position requires a strong background in computational analysis and design optimization in mechanics. The candidate is also expected to be interested in the 3D printing and experimental characterization of composites.
