Engineering Sciences 241: Advanced Elasticity
Spring 2011, Tuesday and Thursday 10:00 am - 11:30 am, Cruft Lab 309. First meeting of the class: 25 January 2011
- Instructor: Zhigang Suo, 617-495-3789, suo@seas.harvard.edu, Pierce Hall 309.
- Office hour: Tuesday 1:00 pm - 2:00 pm.
- No textbook is required.
This is a second graduate course in solid mechanics. The course builds on elements of thermodynamics, and explores coupled mechanical, thermal, electrical and chemical actions. The course draws heavily upon phenomena in soft active materials.

thanks Zhigang Suo
share what we have
Very interesting course
I wish there had been something like this when I was a student! It has been much my frustration that mechanics teaching has not tended towards softer materials, viscoelasticity, etc. I personally never had the chance to take a taught course in any of the subjects that I research or now am trying to teach, in polymer mechanics or time-dependence. Hopefully some time I'll be on sabbatical in the area when you are teaching this sort of module and I could sit in!
thank you for information
thank you for information
Thanks for the detailed lecture
this is the best and most systematic notes on machanics of soft mater I have ever seen, definitly will do great help to my future work!
Thank you for your valuble lectures
Thank you for your valuble lectures
Do you have any lecture about the the effects of both geometric and material nonlinearity in the mechanical dynamics modeling of EPA.

Dynamics of dielectric elastomers
Here are two papers:
Jian Zhu, Shengqiang Cai and Zhigang Suo. Resonant behavior of a membrane of a dielectric elastomer. International Journal of Solids and Structures 47, 3254-3262 (2010).
Jian Zhu, Shengqiang Cai and Zhigang Suo. Nonlinear oscillation of a dielectric elastomer balloon. Polymer International 59, 378-383 (2010).
Useful course
Hi Prof. Suo,
The course seems very inetersting and useful. I think that adding some lectures on recently developed theories in non-classic elasticity such as modified couple stress theory, nonlocal elasticity and strain gradiant theory upgrades the usefulness.

Masoud
Re: Useful course
Dear Masoud: Thank you very much for your suggestion. At the moment the course is built around soft materials, such as elastomers and gels. I will add new parts each time I teach the course (every other year). I welcome all suggestions.
