A new paper in press
in the Journal of the Mechanics and Physics of Solids, with Dr. Gleb Gil Goviazin and co-authors. In a nutshell, this study, which combines high speed photography and thermal imaging, challenges the paradigm that reactive materials' ignition results from shear, showing that normal pressure is the culprit. challenging the paradigm

Let us consider now mode II loading,
Picture of Let us consider now mode II loading,
at a framing rate of 400 kfps and an impact velocity of 42 m/s. Note that this is a one point impact experiment, and the initial notch is loaded parallel to its flank(s) such as to generate mode II (shear). What is interesting is that the struts that fail initially are situated opposite the notch, which fails last. So, here too, the notch (crack) plays no significant role, just as we observed earlier in mode I. Watch on YouTube / Courtesy of Yahav Boim and Dr. Amnon Shirizly.

One point impact - diagonals lattice
Picture of One point impact - diagonals lattice
As promised, here is a first movie of the lattice aluminum structure subjected to one-point impact (not to be confused with direct impact), at a velocity of the order of 35 m/s. A notch is machined on the right side to ensure mode I loading. The trusses that break sequentially are circled in red and the framing rate is 1 million fps, which explains that this is just the onset of fracture, as other struts break later, beyond the duration of the movie (total 180 frames using our Kirana ultra high speed camera, Specialised Imaging Limited).

the chemical and microstructural signature of peri-implantitis on titanium implants' surface
Peri-implantitis is a severe problem of dental implants in which bone regression can reach a point where you need to extract the implant and threads become visible. A disease that affects roughly 30% of the implantees and that has no cure yet. Many mechanisms have been invoked, related to inflammation and release of particles.

Performing static/dynamic (simple) shear tests of metals
is always tricky and fraught with many assumptions. We examine here our Shear Compression 0 (SCS0) specimen through a detailed numerical analysis, and review its advantages and limitations. The paper, co-authored with Itay Levin, is in press in Experimental Mechanics. Stay tuned for more... abstract: making shear simple
