UE 8 - Semestre 1 - Constitutive laws for rheological fluids
Description
◦ The Viscous, Elastic (small and large elastic deformations) and Viscoelastic response.
◦ Simple shear flow of a Newtonian fluid.
◦ Non-Newtonian behaviour : time-independent fluids (rheological models without yield stress, rheological models with yield stress, structural models).
◦ Extensional flow (elongational viscosity).
◦ Time-dependent fluids : memory effects, the mechanism of thixotropy, rheopexy.
◦ Linear viscoelasticity : mechanical models, stress relaxation experiment for a Maxwell fluid, creep and recovery experiment for a Kelvin solid, oscillatory measurements, 1D-models, 3D-models, Mooney-Rivlin model, Ogden model…
◦ Elasto-plasticity, Visco-plasticity, Elasto-visco-plasticity, hyper-elasticity.
◦ The Time-Temperature Superposition Principle.
