The unified mechanics theory (UMT) was used to develop a model to predict the fatigue life of pre-corroded steel samples with BCC structure. Details of the experimental validation are also provided.
Dear Colleagues,
with this message, I would like to advertise 2 post-doctoral research positions at the intersection of electrochemistry and mechanics of materials in my lab at Northwestern University. The two post-doctoral projects will specifically focus on the influence of electrodepositions on the structure, properties, and behavior of soils (project 1) and concrete (project 2).
A postdoctoral position on soft material ionotronics is available in the Silberstein lab (silbersteinlab.com) to start in late summer/early fall of 2020. Expertise in electrochemistry and/or continuum mechanics is desirable. The ideal candidate will also be familiar with polyelectrolytes, gels, and/or ionomers.
Owing to their enormous capacities, Li-S batteries have emerged as a prime candidate for economic and sustainable energy storage. Still, potential mechanics-based issues exist that must be addressed: lithiation of sulfur produces an enormous volume expansion (~80%). In other high capacity electrodes, large expansions generate considerable stresses that can lead to mechanical damage and capacity fading.
I hope some of you may find this work interesting:

I'm looking for postdoc or engineering position in energy storage or power source area (development of supercapacitors, lithium-ion batteries, etc.), where I could apply my knowledge as well as many-years hands-on experience in electrochemistry, materials science and chemical engineering. d.gromadskyi [at] gmail.com
