Dear Colleagues,
I am sharing a recent paper titled "Violation of the Cauchy-Born Rule in multi-principal element alloys" published in Applied Physics Letters. Here is the link to the paper: https://doi.org/10.1063/5.0204091
Sharing a new article "Finite element implementation of Field Crack Mechanics for brittle and ductile fracture" by my Ph.D. student BVSS Bharadwaja at IIT Bombay, which has been accepted for publication in Theoretical and Applied Fracture Mechanics. Also see attached. Thanks to Prof. Amit Acharya for the motivation and discussion.
It is my pleasure to share a new article titled "An Experimentally Informed Continuum Grain Boundary Model" by Syed Ansari (my Ph.D. student at IIT Bombay). This work was performed in collaboration with Prof. Amit Acharya.
An immediate Ph.D. position is available in the Control, Automation, and Mechatronics (CAM) lab at Kent State University, Kent, OH. The program is housed within the College of Aeronautics and Engineering and focuses on Mechatronics Engineering. Ideal candidates will need to have completed their master’s degree in electrical, mechanical, or mechatronics engineering by the end of 202. They must possess a strong foundation in controls and machine learning, along with proficient programming skills in Python and MATLAB.
Dear colleagues,
We invite you to read our article, which informs one about the extent to which resonances can be tuned in metamaterials. More precisely, our work provides tight bounds correlating the Quality-factor with peak absorption in dielectric metamaterials. The article is published in Applied Physics Letters and can be found here: https://doi.org/10.1063/5.0155092
Following the previous Blog entry on 3D fracture and out-of-plane crack structures: the essential role of material disorder, we add here a related manuscript (see also attached PDF):

In classical experiments, it has been found that a rigid cylinder can roll both on and under an inclined rubber plane with a friction force that depends on a power law of velocity, independent of the sign of the normal force. Further, contact area increases significantly with velocity with a related power law. We try to model qualitatively these experiments with a numerical boundary element solution with a standard linear solid and we find for sufficiently large Maugis–Tabor parameter � qualitative agreement with experiments.
