New non-woven paper in IJSS

Our latest journal paper entitled “In-situ X-ray study of the deformation mechanisms of non-woven polypropylene” is now published in the International Journal of Solids and Structures. This paper was authored by PhD student Naigeng Chen, MS student Simge Uzun, and research scientist Margaret Koker.  X-ray scattering and micro computed tomography  were combined with uniaxial mechanical testing to investigate the micromechanical mechanisms governing non-woven strength. These experiments were run on our custom experimental setup at the Cornell High Energy Synchrotron Source (CHESS). We found that the number density of bonds strongly influences the fiber kinematics and overall strength in these meltspun thermoplastics.

Another Summer of Conferences

Prof Silberstein kicked off the summer at the annual Society for Experimental Mechanics conference where she gave of talk on non-woven mechanics focusing on work by PhD student Naigeng Chen. Along with with first author Elizabeth Jones, Prof Silberstein was presented the Hetenyi Award for best paper in Experimental Mechanics from the previous year.

That same week Naigeng presented a poster of his latest non-woven experimental technique at the annual CHESS users meeting on the Cornell campus.

In early August Prof Silberstein gave an invited talk on mechanochemistry at the US-Japan Young Researcher’s symposium on Mechanics of Materials hosted by
Stony Brook University.IMG_2374

Finally, Prof Silberstein, Naigeng, and PhD student Suwon Bai headed up to Montreal for the International Congress of Theoretical and Applied Mechanics  (aka the summer olympics of mechanics).  Prof Silberstein and Naigeng each gave talks and Suwon presented a poster.

June Conference Bonanza

Graduate student Meenakshi Sundaram presented his work on interfacial mechanochemistry at the biannual International Conference on Self-Healing Materials (ICSHM).

Professor Silberstein presented a range of the group’s mechanochemistry research at the Society for Experimental Mechanics (SEM) annual conference, ICSHM, and ASME’s Applied Mechanics and Materials Conference (McMat).
