As the rest capsule membrane aspect ratio increases, the capsules become increasingly vulnerable to a buckling instability. This buckling behavior is concomitant with a sudden increase in the effective Viscosity and a near disappearance of any near-wall capsule-free layer. The microstructure dynamics suggest elongated capsules make significant rotational contributions that disrupt organized flow, as computed by their rotlet capsule-capsule interactions. 000014674 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000014674 653__ $$a 000014674 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000014674 720__ $$aBryngelson, Spencer 000014674 8560_ $$ffischerc@itam.cas.cz 000014674 8564_ $$s155915$$uhttps://invenio.itam.cas.cz/record/14674/files/TS.FM12-1.03.pdf$$yOriginal version of the author's contribution as presented on CD, page 1256, code TS.FM12-1.03 . 000014674 962__ $$r13812 000014674 980__ $$aPAPER
