This is our recent work on the design of fatigue-resistant hydrogel adhesion. In this work, we show that fatigue-resistant hydrogel adhesion can be achieved by anchoring ordered nanocrystalline domains at the interface. This method is applicable to glass, ceramic, titanium, aluminum, stainless steel, and even elastomers including PU and PDMS. We also demonstrate its potential applications as endurant hydrogel coatings for versatile engineering materials with complex geometries.

Defects, a ubiquitous feature of ordered media, have certain universal features, independent of the underlying physical system, reflecting their topological, as opposed to energetic properties. We exploit this universality, in conjunction with smoothing defects by "spreading them out," to develop a modeling framework and associated numerical methods that are applicable to computing energy driven behaviors of defects across the amorphous-soft-crystalline materials spectrum. Motivated by ideas for dealing with elastic-plastic solids with line defects, our methods can handle order parameters that have a head-tail symmetry, i.e. director fields, in systems with a continuous translation symmetry, as in nematic liquid crystals, and in systems where the translation symmetry is broken, as in smectics and convection patterns. We illustrate our methods with explicit computations.

This afternoon I gave a Harvard Applied Mechanics Colloquium. Here is the abstract, along with the slides.  The slides themselves just serve as an outline of ideas.  You can find original papers on our group website. 

Dear Colleagues,

Please consider submitting an abstract to the Symposium 15 "Modeling and Design of Architected Materials" at the 10th International Conference on Multiscale Materials Modeling that will take place in Baltimore in October 19-23, 2020.

The deadline for abstract submission is March 1.

This symposium will discuss the latest advances in computational design and modeling of architected materials.

PLEASE NOTE: this position is only open to holders of Canadian, US or EU citizenship, or Canadian PR (permanent residence card) holders.

KEYWORDS: HIGH-SPEED IMPACT, COMPUTATIONAL MODELING, ADVANCED COMPOSITE MATERIALS, COMPUTATIONAL DAMAGE MECHANICS

Dear colleagues,

A position exists, for a Research Assistant/Associate in the Department of Engineering, to conduct research into Mechanics of lattice materials. The post holder will be located in Central Cambridge Cambridgeshire, UK. There is an opportunity to invent interpenetrating lattice materials in order to design SOFT and HARD meta-materials of any given stiffness, strength and toughness. The actuation response due to seepage of a liquid through the lattice needs to be modelled by making use of experimental results from within the group.

The School of Engineering at the Pontificia Universidad Católica de Chile, one of the leading engineering educational institutions in Latin America and ranked among the top four emerging leaders for engineering education worldwide, invites outstanding candidates for a full-time faculty position in the area of Multiscale Engineering Mechanics at the Department of Mechanical and Metallurgic Engineering. 

A new PhD position is open at the Université Gustave Eiffel, France. The project will focus on the investigate the influence of ground liquefaction on the behavior of homogeneous embankment under seismic loading. The technical strategy of this study will be a combined approach of 70% physical centrifuge modeling and 30% numerical modeling. The experimental study will provide important proof on the physical phenomena and essential data for numerical modeling; Being the complimentary of experimental work, the calibrated numerical model will be used to carry out parametric and case studies.

We are looking for an energetic and highly motivated Ph.D. student to work on Theoretical and Computational Micromechanics of Soft Biological Materials. The project will be focused on studying biological gels and cytoskeletal mechanics.

Dear Colleagues,

We would like to remind you to submit an abstract to the minisymposium #22 Multiscale Modeling of Polymers and Soft Materials to be held at the 10th International Conference on Multiscale Materials Modeling. The deadline for abstract submission is March 1st, 2020. The conference will be held on October 19-23, 2020 at the Renaissance Harborplace Hotel, Baltimore, MD, U.S.A. Additional information about the conference can be found on the webpage https://mmm2020.jhu.edu/

A PhD studentship in the field of bioinspired materials and structures is available in the Department of Mechanical Engineering at Kingston University London.

The Hector Fellow Academy offers you the opportunity to realize a self-developed research project under supervision Prof. Peter Gumbsch. He is one of the Hector Fellows, a community of outstanding professors from different research institutions across Germany working in STEM-subjects, medicine, and psychology.

The extraordinary mechanical properties of graphene were measured on very small or supported samples. In our new paper published in Nature Communications, by developing a protocol for sample transfer, shaping and straining, we report the outstanding elastic properties and stretchability of free-standing single-crystalline monolayer graphene under in situ tensile tests.

Patients with AS exhibit blood and elevated protein levels in their urine, inflamed kidneys, and many other abnormalities.

A Special Issue entitled "Nanofabrication, Atomic and Close-to-atomic Scale Manufacturing" for the journal Nanomanufacturing and Metrology is now open for submission:
