Viscoelasticity and elastoplasticity in the power law creep and yielding of gels and fibre network materials under stress
Michael J. Hertaeg, Suzanne M. Fielding
We study computationally the creep and yielding of athermal gels and fibre network materials under a constant imposed shear stress, within a minimal model of interconnected filamen…
Elastic turbulence in highly entangled polymers and wormlike micelles
Theo A. Lewy, Suzanne M. Fielding, Peter D. Olmsted +1
We show theoretically that an initially homogeneous planar Couette flow of a concentrated polymeric fluid is linearly unstable to the growth of two-dimensional (2D) perturbations,…
Toughness of double network hydrogels: the role of reduced stress propagation
Samuel B. Walker, Suzanne M. Fielding
Double network hydrogels show remarkable mechanical performance, combining high strength and fracture toughness with sufficient stiffness to bear load, despite containing only a lo…
Simple and effective mechanical cloaking
Suzanne M. Fielding
We show theoretically that essentially perfect elastostatic mechanical cloaking of a circular inclusion in a homogeneous surrounding medium can be achieved by means of a simple clo…
Shear banding as a cause of non-monotonic stress relaxation after flow cessation
Vanessa K. Ward, Suzanne M. Fielding
Recent flow cessation experiments on soft materials have shown a counter-intuitive non-monotonic relaxation of the shear stress: following the switch-off of a steady imposed shear…
Non-monotonic constitutive curves and shear banding in dry and wet granular flows
Christopher Ness, Suzanne M. Fielding
We use particle simulations to map comprehensively the shear rheology of dry and wet granular matter comprising particles of finite stiffness, in both fixed pressure and fixed volu…
