Summary

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations. In this dissertation, we design non-linear building blocks to realize a non-Abelian metamaterial whose response is sequence-sensitive. We study the behaviour of such metamaterials through simulations and experiments using existing mathematical and engineering frameworks such as finite state machines and Boolean logic circuits. We discover that the non-Abelian metamaterial possesses information processing and storage capabilities: it behaves like a simple computer. This opens up new avenues to realize mechanical computing and memory devices with a complex emergent response.

PhD dissertations

Approximately one week after the defence, PhD dissertations by Leiden PhD students are available digitally through the Leiden Repository, that offers free access to these PhD dissertations. Please note that in some cases a dissertation may be under embargo temporarily and access to its full-text version will only be granted later.
