Our latest paper is published in PRL today (). Coincidentally, today also marks the first day of my journey as an assistant professor at
@GeorgiaTech
---a remarkable and memorable way to start this new chapter in my career!
"Nonlocal Intrinsic Fracture Energy of Polymerlike Networks" appears in
@PhysRevLett
. We show that the intrinsic fracture energy of polymer-like networks is due to nonlocal dissipation, different from the classical Lake-Thomas model.

Our new project is in
#ICML2023
! We use neural networks to learn the constitutive laws of a material only based on one recorded video. It can be particularly interesting in the field of material science for rapid, high throughput, or even contactless property measurements.
(Surprise?) Our neural-PDE solver generalizes to extremely out-of-distribution geometries, boundary conditions, and even multi-physics. Hint: we learned a constitutive model.

This is so ridiculous. "Dr. Shi and Dr. Zhu also found that the presence of a single Asian student in a class amplifies teachers’ negative assessments of Black and Hispanic students vis-à-vis white students."
“Asian American students who have earned admission to Harvard are smart, promising, and have no doubt worked very hard. But in ways . . . they may have also benefited from their racial status long before they applied,” writes sociology Professor

Can we design geometry of the shell such as it can be loaded with small force but long loading distances, when released it can generate explosive force (much larger than the loading force) to grab things? It requires some non-reciprocal design probably.

Nice work. I guess we are going the thing direction. I see that you also start to transit from choosing model from a library to use neural network. I would see here the challenge is how to make sure the NN based constitutive law is stable under different testing scenarios.

With such unified representation, this work lays a foundation for inverse design of general metamaterials, i.e., automatically produce the microstructure design for the desired properties.

The main challenge of this paper is that we need to simulate very very very large networks with more than 40 million nodes. With a coarse grain idea from
@chase_hartquist
and implementation advice from Bohan Wang (CSAIL, MIT), we are able to simulate them on desktops.

If such a virus breakout happens in New York, Houston or Chicago, will the government lockdown the city immediately and ban all kinds of transportation in-and-out? Probably not. New York now has 150k cases and you can still leave New York. Wuhan was lockdown with only 800 cases.
