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…

Elasticity of fibrous networks under axial prestress
Mahsa Vahabi, Abhinav Sharma, Albert James Licup +4
We present theoretical and experimental studies of the elastic response of fibrous networks subjected to uniaxial strain. Uniaxial compression or extension is applied to extracellu…
