Four types of discretely assembled mechanical metamaterials. Left to right: Rigid, compliant, auxetic, and chiral. (A) As-molded face parts. (B) Single voxel, front view. (C) A 2 × 2 × 2 cube, front ...

Crashworthiness may be defined as a structure’s ability to provide controlled energy absorption and protect its occupants from excessive forces and peak accelerations in a crash. In general, the ...

In my two previous columns, I discussed the lower and intermediate levels of the building block approach for crashworthiness testing and analysis of composite structures. I focused on the commercial ...
