Modelling of Phase Transforming Cellular Material (PXCM)
28 Aug 2017 | | Contributor(s):: Chidubem Nuela Enebechi, Yunlan Zhang, David Restrepo Arango, Pablo Daniel Zavattieri, Nilesh Mankame
Phase transforming cellular materials (PXCMs) are a new class of materials that can go through large deformation and return to their original configuration. Currently, there are reliable cellular materials that can resist large deformation, for example, honey comb; however, when these materials...
