| Abstract
| - A nonequilibrium molecular dynamics simulation of the response of dimyristoylphosphatidylcholine (DMPC)bilayers to a solvent shear flow is presented. Application of shear flow to planar, stationary DMPC bilayersresults in a redistribution of the membrane density profile along the bilayer normal due to the alignment ofthe lipids in the direction of flow and an increase in average lipid chain length. An increase in the intermolecularand intramolecular order of the lipids in response to the shear flow is also observed. This study providesgroundwork for understanding the mechanism of the full response of lipid bilayers to externally imposedsolvent shear flows, beginning with the response in the absence of collective lipid motions such as undulationsand bilayer flow.
