I just found a topic which might be of your interest.
Attached please find a paper on a new type of mechanical metamaterials, whose topology make them resistant to local buckling. This paper is published in PNAS, with an impact factor of 9.661. The paper has been cited by 58 times since 2015.
Prof. J. Oliver from Spain performed multiscale modeling of metamaterials. Below please find his presentation on Youtube:
Liang, thanks a lot for sharing this. Since MSG/SwiftComp does not require assumption of the microstructure, it should be able to handle any materials. We need to add more physics into MSG/SwiftComp. Finding more applications for MSG is always welcome.

I have been collecting information on mechanical metamaterials these days. Interestingly, I found that Prof. Glaucio Paulino at Georgia Tech had been working on this topic for several years. Attached please find his paper on origami metamaterials, published in PNAS. The paper has been cited for 71 times since 2015.
I’d like to introduce another big family of mechanical metamaterials, auxetic materials. Auxetic materials are materials with negative Poisson's ratio (auxetics). To my knowledge, auxetic materials were first found by Dr. Lakes:
Lakes, R.S. (1987-02-27), "Foam structures with a negative Poisson's ratio", Science, 235 (4792): 1038–40.
Since MSG/SwiftComp does not make any assumption regarding the microstructure, it should be able to handle any microstructures of course including those what Liang pointed out.

Below please also find mechanical metamaterial on Wikipedia:
https://en.wikipedia.org/wiki/Mechanical_metamaterial
Materials with negative Poisson's ratio also belong to such materials.
Should you have any thoughts, comments, or suggestions, please feel free to discuss.

I believe that SwiftComp, or specifically, Dr. Zheng Ye's work on corrugated plate, can handle such structures well.

More information can be found in attached ppt file. Below please find videos of auxetic materials having different structures:
Here are two additional remarks
