Normal stresses in semiflexible polymer hydrogels
Mahsa Vahabi, Bart E. Vos, Henri C. G. de Cagny +3
Biopolymer gels such as fibrin and collagen networks are known to develop tensile axial stress when subject to torsion. This negative normal stress is opposite to the classical Poy…
Porosity governs normals stresses in polymer gels
Henri C. G. de Cagny, Bart E. Vos, Mahsa Vahabi +5
When sheared, most elastic solids such as metals, rubbers and polymer hydrogels dilate in the direction perpendicular to the shear plane. This well-known behaviour known as the Poy…
S-Shaped Flow Curves of Shear Thickening Suspensions: Direct Observation of Frictional Rheology
Zhongcheng Pan, Henri de Cagny, Bart Weber +1
We study the rheological behavior of concentrated granular suspensions of simple spherical particles. Under controlled stress, the system exhibits an S-shaped flow curve (stress vs…
Rheology of sedimenting particle pastes
Abdoulaye Fall, Henri de Cagny, Daniel Bonn +4
We study the local and global rheology of non-Brownian suspensions in a solvent that is not density-matched, leading to either creaming or sedimentation of the particles. Both loca…
