ABAQUS is unable to interpret your subroutine as an implementation of plasticity. You get PE and PEEQ only if you use the standard command *PLASTIC.

In reply to Internship Positions in Schlumberger-Doll Research in Cambridge MA

Please note that a new version of the internship job description focusing on computation mechanics, with preferred skills defined, is now attached. The earlier job description (still attached as before), with focus on robotics, is still relavant. We have both positions available to fill for 2019.

We thank all students who have submitted their applications. They are currently under review. Both positions are still open as of now. - Tianxiang, Jan 14, 2019

In reply to Hi Qihan,

Hi Tongqing,

Very good question. The bending you mentioned should come from the residual stress in the bulk material. The interfacial layer is probably too thin to cause anything noticable for the size of a common device. I guess the bending should be gone if you can control the drying of the gel during the bonding process?

In reply to Journal Club for December 2018: Bonding hydrophilic and hydrophobic soft materials for functional soft devices

Hi Qihan,

I have learned a lot form your interesting and inspiring work. My question is would any residual stress exist after the adhension. Some students here found that after adhension of two layers, the bilayer bent a lot. Is the stress good or bad for the adhension?


Congratulations Guoying!
