Propagating plastic instabilities in planar architectured materials

Our latest paper in International Journal of Solids and Structures deals with harnessing material instabilities through inner material architecture, here in the case of 2D planar lattices. ( https://doi.org/10.1016/j.ijsolstr.2020.05.027 )

These results are the work of Antoine-Emmanuel Viard, currently doing his PhD in collaboration between PIMM and Centre des Matériaux (MINES-ParisTech, PSL University) (Dr. Samuel Forest).

These results open the path for the design of architectured materials with instability-driven behavior, i.e. actuators, unfolding structures, etc., as well as bespoke materials able to accentuate or mitigate the onset and propagation of instabilities. In this work we looked specifically to Piobert-Lüders plastic instabilities, but the results will be extended to shape-memory alloys for reversible applications.

This study is funded by Agence Nationale de la Recherche through the ANR ALMARIS project (Grant No. ANR-16-CE08-0001).
