@USA_China_Talk Shame on you

[Ruobing Bai @RuobingB]

Submit abstracts by Oct 25! @chenchao04 (3M), Hyunki Kim (3M), and I are organizing a focus session on “Mechanics and Polymer Physics of Soft Adhesives (@APS_DPOLY, @ApsDsoft)”, at the 2025 APS March Meeting. Invited speaker features @HyunwooYuk @SanaHeal. https://t.co/Y5FC9jFweg

@zhigangsuo @rhpume It’s such a great pleasure and honor to host you in 3M campus. Thank you for the great talk in fracture and fatigue, as well as the insightful discussion, which were really educational and inspiring in 3M!

[Zhigang Suo @zhigangsuo]

Today I visited 3M, gave a seminar, and had technical discussions.

At lunch I asked, “What makes 3M work?”

“Culture,” a longtime 3Mer replied. It is heartwarming to see people take pride in their organization.

That culture was articulated a long time ago.

@Crosby__Group @UMassPSE @aljcrosby Congratulations Al!

[Crosby Research Group @Crosby__Group]

Exciting news! 🎉 Congratulations to Prof. Al Crosby for starting as the head of Polymer Science and Engineering @UMassPSE! We from Crosby group are very proud of you and excited to see your passion for science achieving great heights in academic excellence! @aljcrosby #research

@ShiQingWang4 @QihanLiu1 @zhigangsuo @RuobingB The length scale was derived from the 1/r crack-tip singularity of the strain energy density. The original analysis of this energy singularity was firstly shown in Jim Rice’s HRR paper, so we assume it’s valid at least for metals. His approach was very generic based on J-integral

[Chao Chen @chenchao04]

@SVDODD @zhigangsuo @ShiQingWang4 @RuobingB I think this length as a material property does rely on material chemicals which defines a material.

[Chao Chen @chenchao04]

Fascinating! Thank you for sharing.

I've done noodle fracture and energy dissipation research. https://t.co/sc9PNNXPRH

A creeping but not necking material can make Lamian/Ramen/pulled noodles. Many noodle experts from Suo group. @RuobingB @KejieZhao

[Chao Chen @chenchao04]

A fun demonstration for solid mechanics class. A play-dough shows necking.

@KejieZhao @DrJiaweiYang If you guys can start an International Journal of Educational Mechanics 😄

And the slime creeps.

[Chao Chen @chenchao04]

A slime doesn’t.

The @UMassPSE community is looking forward to this Friday's virtual seminar on underwater adhesion! Hosted by @aljcrosby - Professor Marleen Kamperman is visiting from @univgroningen #UMassPSE #polymers

[Chao Chen @chenchao04]

@zhigangsuo @CretonCost @EnduricaWill @EnduricaChris @yecheng_w @jasongsteck @SammyHassan_ @Junsoo_twit @ShiQingWang4 We had a lot of discussion on the physical significance of this dimension, but it was not clear. We decided a brief mention in the flaw sensitivity paper— We hid behind the giant. It becomes clearer when related to the intrinsic dissipation.

[Chao Chen @chenchao04]

Thank you all for having me working in the program!

[Al Crosby @aljcrosby]

HFSP is such a great program. Love being a part of this team! @Beverley_CUBG and Michel Milinkovitch!

[Chao Chen @chenchao04]

@DrJiaweiYang Great work!
