TItLE:		Buckling, Crumpling, And Tumbling Of Semiflexible
 		   Sheets in Simple Shear Flow


SPEAKER:	Kevin Silmore  (MIT)


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 in the flow-gradient 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.


BIO:  Kevin Silmore is a Department of Energy Computational Science Graduate 
Fellow and PhD Candidate in Chemical Engineering and Computation at MIT. 
Working with James Swan and Michael Strano, his research lies at the 
intersection of nanomaterials, soft matter physics, and numerical methods 
development.  Kevin graduated with a BSE in Chemical and Biological Engineering 
from Princeton University in 2016.
