Dear All, to increase the visibility of our research, we have created a linkedin group at, and a youtube channel  at with the same title: Multiscale Structural Mechanics. You are welcome to join the linkedin group and subscribe to the youtube channel. 

Dear All,

I finally completed an introduction to micromechanics based on the lecture notes I have for the multiscale structural mechanics course. The article can be found from Please let me know your feedback so that I can explain things better or add more important material which is missing. 

Thanks in advance for your help!


Dear All, 

I wrote the imechanica Journal Club article entitled Mechanics of Structure Genome this month. You are welcome to read it and leave your comments for discussions. The article can be found at Any suggestions/questions/comments are welcome.
