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…
Inertial motion of incompressible continua
Francesca Berlinghieri, Giulio G. Giusteri
We study the inertial motion of incompressible continua within a geometric and variational framework, extending the classical Arnold-Ebin-Marsden theory from the group of volume-pr…
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…
Variationally mimetic operator network approach to transient viscous flows
Laura Rinaldi, Giulio Giuseppe Giusteri
The Variationally Mimetic Operator Network (VarMiON) approach is a machine learning technique, originally developed to predict the solution of elliptic differential problems, that…

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…
On the Noisy Road to Open Quantum Dynamics: The Place of Stochastic Hamiltonians
Pietro De Checchi, Federico Gallina, Barbara Fresch +1
Stochastic evolution underpins several approaches to the dynamics of open quantum systems, such as random modulation of Hamiltonian parameters, the stochastic Schrodinger equation…

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.…

Gennaro Ciampa, Giulio G. Giusteri, Alessio G. Soggiu
We introduce models for viscoelastic materials, both solids and fluids, based on logarithmic stresses to capture the elastic contribution to the material response. The matrix logar…
Periodic rhomboidal cells for symmetry-preserving homogenization and isotropic metamaterials
Giulio G. Giusteri, Raimondo Penta
In the design and analysis of composite materials based on periodic arrangements of sub-units it is of paramount importance to control the emergent material symmetry in relation to…
