A numerical study to analyze the interplay of Weissenberg number and viscosity ratio in a log-strain tensorial model for viscoelastic fluids
Nehal Dash, Ramon Codina, Giulio G. Giusteri
We present a computational study aimed at exploring the different and independent roles of the Weissenberg number and of the ratio between the polymeric and solvent viscosity contr…
Morphogenesis driven by nematic defects in active biological networks
Silvia Paparini, Giulio G. Giusteri, L. Angela Mihai
Cellular morphogenesis, the process by which biological tissues acquire shape and structure, remains a fundamental challenge in understanding pattern formation and the coordinated…
Modelling the passive and active response of skeletal muscles within the adapted Voigt representation framework
Sara Galasso, Giulio G. Giusteri
We present a constitutive model for the passive and active response of skeletal muscles. At variance with more classical approaches, the model is developed exploiting adapted Voigt…
Shape instabilities driven by topological defects in nematic polymer networks
Silvia Paparini, Giulio G. Giusteri, L. Angela Mihai
Liquid crystalline networks (LCNs) are stimuli-responsive materials formed from polymeric chains cross-linked with rod-like mesogenic segments, which, in the nematic phase, align a…
Evolution of local relaxed states and the modelling of viscoelastic fluids
Muhanna A. H Alrashdi, Giulio G. Giusteri
We introduce a class of continuum mechanical models aimed at describing the behaviour of viscoelastic fluids by incorporating concepts originated in the theory of solid plasticity.…
Shear jamming and fragility of suspensions in a continuum model with elastic constraints
Giulio G. Giusteri, Ryohei Seto
Under an applied traction, highly concentrated suspensions of solid particles in fluids can turn from a state in which they flow to a state in which they counteract the traction as…
Normal stress differences in dense suspensions
Ryohei Seto, Giulio G. Giusteri
The presence and the microscopic origin of normal stress differences in dense suspensions under simple shear flows are investigated by means of inertialess particle dynamics simula…
Microstructure and thickening of dense suspensions under extensional and shear flows
Ryohei Seto, Giulio G. Giusteri, Antonio Martiniello
Dense suspensions are non-Newtonian fluids which exhibit strong shear thickening and normal stress differences. Using numerical simulation of extensional and shear flows, we invest…
