Entropic Elasticity at the Sol-Gel Transition
The sol-gel transition is studied in two purely entropic models consisting of hard spheres in continuous three-dimensional space, with a fraction p of nearest neighbor spheres tethered by inextensible bonds. When all the tethers are present (p = 1) the two systems have connectivities of simple cubic and face-centered cubic lattices. For all p above the percolation threshold pc, the elasticity h...
متن کاملAnisotropic elasticity of magnetically ordered agarose gel.
The physical properties of agarose gel prepared under strong magnetic fields were investigated. The storage modulus was measured by the reflection method with an ultrasonic pulse. The measurement results of the gel's elasticity indicate that agarose gel has anisotropic properties. The elasticity and its anisotropy depend on the concentration of the gel and the magnetic field to which it is expo...
متن کاملNonlinear elasticity and cavitation of a triblock copolymer gel.
Polymer gels are subjected to large-strain deformation during their applications. The gel deformation at large-strain is non-linear and can often lead to failure of the material. Here, we report the large-strain deformation behavior of a physically cross-linked, swollen triblock copolymer gel, which displays unique strain-stiffening response at large-strain. Investigations were performed using ...
متن کاملThe Elasticity of Elasticity
In this talk I assert that the usual interpretation of what one means by “elasticity” is much too insular and illustrate my thesis by introducing implicit constitutive theories that can describe the nondissipative response of solids. I show that response which was hitherto untenable within the context of Cauchy or Green Elasticity are not only possible, they can explain phenomena that have thus...
متن کاملShear Thickening and Gel Elasticity in a Colloidal System with Attractive Interactions
Dilute oil dispersions of carbon black particles with attractive Van der Waals interactions display shear thickening in two distinct regimes. The first occurs at low shear rates, γ̇c1 ≈ 100s−1 along with the formation of vorticity aligned shear-induced structures. The second high shear regime with γ̇c2 ≈ 102−3s−1 is driven by hydrodynamic breakup of clusters. Pre-shearing in the high rate shear t...
