Hierarchically enhanced impact resistance of bioinspired composites, Gu, Takaffoli, Buehler, Advanced Materials, 2017
Novelty/impact/significance:
A methodology combining simulation, additive manufacturing of biomimetic structures, and mechanical testing is developed, and the function of structural hierarchy is explicated. The findings provide insightful guidance for designing future protective materials and devices.
Dear iMechanicians,
I hope some of you find our recent JMPS paper interesting. We combine phase field fracture, hydrogen transport and strain gradient plasticity to provide a modern rationale to the mechanism of hydrogen enhanced decohesion.

Please contact me and Daniel Balint, should you be interested in contributing an authoritative review or white paper.
Best!

This upcoming webcast is ideal for anyone working on orthopaedics simulation, particularly in revision surgeries. It should also be a good opportunity to learn about some of the altest image-based methods for working with CT data, for example with the hip.

If you are interested in elastomers and electric vehicles, check out this link to RIEG webinar on Elastomer use in Electric Vehicles. There were 4 talks covering elastomer requirements for EVs, mounting system design for EVs, use of carbon black in EV applications, and EV mount integrity digital twin. Enjoy!
All materials are anisotropic, that's a fact. Like the fact that all materials have a nonlinear response. This we can't deny. Still enormous progress has been made by assuming both isotropy and linear elasticity. The success, as we all know, is due to the fact that many construction materials are very close to being both isotropic and linear. By definition materials may be claimed to be isotropic and linear, provided that the deviations are held within specified limits. Very often or almost always in structural design nearly perfect linearity is expected.
1 Ph.D. position is open for a research project related to bioinspired mechanics of cutting and piercing of soft homogeneous and heterogeneous (composite) materials. The position is under the supervision of Prof. Mattia Bacca in the Department of Mechanical Engineering at UBC, Vancouver – Canada. It is funded by the Human Frontiers in Science Program, in collaboration with the Bioengineering Department at Imperial College London and the Department of Ecology at the University of California.
EML Webinar on 19 August 2020 will be given by Professor Markus Buehler, MIT via Zoom meeting. Discussion leader: Professor Grace Gu, UC Berkeley

Dear colleagues, I hope this note finds you well despite the significant challenges that 2020 has brought. I am seeking to hire two post-docs for a new multidisciplinary project in my group titled "Distributed intelligence in kirigami-inspired flexible architectures". In this project we aim to implement ideas such as logic, information processing, and autonomy in materials.
The COVID-19 pandemic created huge demand of relevant medical and personal protective equipment (PPE) and put unprecedented pressure on the healthcare system within a very short span of time. Moreover, the supply chains system faced extreme disruptions as a result of the frequent and severe lockdowns across the globe. In this situation, additive manufacturing (AM) becomes a supplementary manufacturing process to meet the explosive demands and ease the health disaster worldwide.
