Unconventional rheological properties in systems of deformable particles.

At large strains, these systems experience an unconventional shear weakening transition characterized by an increase in the mechanical energy and a drastic drop in shear stress, which stems from the emergence of shortranged tetratic order. In these weakened states, the contact network evolves reversibly under strain reversal, keeping memory of its initial state, while the microscopic dynamics is irreversible. | URI: | https://hdl.handle.net/10356/159654 | ISSN: | 1744-683X | DOI: | 10.1039/D1SM00936B | Schools: | School of Physical and Mathematical Sciences School of Chemical and Biomedical Engineering |
