Dear Colleagues,
Please find our new paper titled "Photochemical-induced phase transitions in photoactive semicrystalline polymers" published in Physical Review E. We used phase field model to investigate photochemical phase transitions in semicrystalline polymers.

Dear Colleagues,
Here is our recent paper published in EML on collective behavior in solid-state photoreaction. Combining statistical mechanics and continuum mechanics, we build a model to predict and explain multiple collective behaviors reported in experiments of solid-state photoreaction for the first time.

Dear Colleagues,
Our paper on theory of photomechanical elastomers has been published in JMPS. We explored the interplay between mechanical stress, light-induced reaction, and large deformation in photoactive nematic elastomers. You can find 50 days' free access here: https://authors.elsevier.com/c/1bceu57Zjx1Q7

Here are the elasticity notes of Eli Sternberg over many years as he taught AM 135 at Caltech. I had access to them when I was working with Prof. Kaushik Bhattacharya at Caltech during postdoc. Prof. Bhattacharya suggested making the notes publicly available via iMechanica, and below is a short note from him.
My group in the Department of Mechanical and Industrial Engineering at Northeastern University has multiple fully funded PhD positions, starting Spring/Fall 2021. Successful candidates will be working in the broad area of mechanics and/or materials, including but not limited to biomimetic and biological materials, soft active materials, soft robotics, multiphysics characterization, design, and functionalization. Research will be focused on the combination of theory and experiment.
Dear colleagues,
Here is our recently published review article about hydrogel adhesion. Hydrogel adhesion has undergone transformative advances in the last few years. This review article describes these advances, and outlooks future opportunities.

Dear colleagues,
Here is our recent paper about designing flaw-insensitive hydrogels that resist fatigue crack growth.
Title: Flaw-Insensitive Hydrogels under Static and Cyclic Loads
Authors: Ruobing Bai, Jiawei Yang, Xavier P. Morelle, and Zhigang Suo*
Abstract
Here is our review article on fatigue of hydrogels. This is the first review of the subject. We review fatigue as any failure of material under prolonged static or cyclic loads. The paper starts with fundamentals, and covers a broad field, yet leaving a lot of interesting questions to be answered. The paper links the chemistry and mechanics of hydrogels.
