AI Article Synopsis
- 2D materials like graphene and transition metal dichalcogenides are increasingly used in creating advanced materials, but our understanding of how these materials behave in fluid flow is still developing.
- This study utilizes numerical simulations to analyze athermal semiflexible sheets in shear flow, focusing on their buckling instabilities and chaotic behaviors based on their initial orientations.
- Key findings include that these sheets can buckle in various ways depending on their stiffness, and they typically fold or crumple before tumbling, without stretching further when more shear is applied.
Article Abstract
As 2D materials such as graphene, transition metal dichalcogenides, and 2D polymers become more prevalent, solution processing and colloidal-state properties are being exploited to create advanced and functional materials. However, our understanding of the fundamental behavior of 2D sheets and membranes in fluid flow is still lacking. In this work, we perform numerical simulations of athermal semiflexible sheets with hydrodynamic interactions in shear flow. For sheets initially oriented near the flow-vorticity plane, we find buckling instabilities of different mode numbers that vary with bending stiffness and can be understood with a quasi-static model of elasticity. For different initial orientations, chaotic tumbling trajectories are observed. Notably, we find that sheets fold or crumple before tumbling but do not stretch again upon applying greater shear.
