The ICME Conference 2020, a HxGN LIVE event is a 3-days intensive online conference on October 6-8, 2020 for executives, R&D, manufacturing professionals, engineers, and designers to learn, explore and share about Integrated Computational Materials Engineering (ICME) to enable companies to blur the boundaries between manufacturing, materials and part performance for the optimal design of innovative quality products.
Damage-tolerant architected materials inspired by crystal microstructure, Pham, Liu, Todd, Lertthanasarn, Nature, 2019
Novelty/impact/significance:
Unlike most architected materials with periodic identical units and thus immediate collapse upon yielding, novel crystal-inspired structures by utilizing the toughening/strengthening mechanisms of crystalline metals (e.g., grain boundaries, precipitates and phases) are developed to possess superior robustness and damage-tolerance.
EML Webinar on 23 September 2020 will be given by Marc Geers, Eindhoven University of Technology, Discussion leader: Laurence Brassart, Oxford University.
Title: Title: Multi-scale homogenization of materials with an emergent macroscopic behaviour
Time: 7 am California, 10 am Boston, 3 pm London, 10 pm Beijing on 23 September 2020
Tribological behavior of graphene layers has been a focus of intensive research interest since its crystal lattice structure can be exploited to achieve incommensurate contact, leading to nearly zero friction, namely structural superlubricity. However, wrinkling undulations are omnipresent on graphene and difficult to be completely eliminated, which inevitably resists superlubricity in reality. Here, we explore how the presence of surface wrinkles affects nanotribological behavior of graphene sliding systems.
The Labortory of Soft Materials Mechanics and Manufacturing (https://www.engineering.pitt.edu/LASM3/) is recruiting PhD candidates starting either on Spring or Fall 2021. Students with expertise in the following areas are especially valued:
1. Thermodynamics of solids
2. Polymer synthesis
3. Developing customer experimental setups
PhD positions are available in the field of 3D printed composite materials for impact mitigation and acoustic attenuation. The research work will have both computational and experimental components. Individuals interested in 3D printed polymer composites, multiscale material modelling, performance of composites under high strain rates and experimental mechanics are encouraged to apply. The position starts early January 2021. The students will be enrolled in the Department of Civil and environmental Engineering at the University of Rhode Island.
Ericksen's problem consists of determining all equilibrium deformations that can be sustained solely by the application of boundary tractions for an arbitrary incompressible isotropic hyperelastic material whose stress-free configuration is geometrically flat. We generalize this by first, using a geometric formulation of this problem to show that all the known universal solutions are symmetric with respect to Lie subgroups of the special Euclidean group. Second, we extend this problem to its anelastic version, where the stress-free configuration of the body is a Riemannian manifold.
The Special Issue "Advances in Elastic Micro-Structured Systems and Metamaterials", that will be published in Applied Sciences (Impact Factor: 2.474), is open to receive submissions for peer-review and possible publication.

A joint postdoctoral position in “Topology Optimization of Additively Manufactured Composites” is available between Embry-Riddle Aeronautical University (ERAU) and University of Texas at Austin (UT Austin). The applicant must currently be in the U.S.
A few days ago I had a good discussion with a dear colleague on the topic of the current state of scholarship in mechanics and the education of the new generation of mechanicians. During the past few decades most mechanics researchers have limited their activities to the writing of papers and research proposals. This because the “reward system” places little value to the authoring of monographs and textbooks. In fact the number of quality books produced during this period pales in comparison to those written by the giants of mechanics, including Timoshenko, Truesdall, etc.
