AIM
To learn the flow characteristics of polymers
OBJECTIVES
To understand Mechanical behaviour of polymeric materials under applied load for short
tern and long term Flow behavior of polymer melts and the experimental techniques for
measuring the rheological properties.
UNIT I 12
Introduction to Rheology – types of mechanical deformation – Elastic materials – Vicous
materials – Viscoelasticity – effect of rate of strain, temperature and time on mechanical
behaviour of polymeric materials – creep – stress relaxation – Boltzman principle – time
temperature super position principle – WLF equation.
UNIT II 12
Mechanical models – stress strain response of spring and dashpot – viscoelstic models
Maxwell element – Voigt kelvin element – response to creep and stress relaxation –
four-parameter model – dynamic mechanical properties – behavior of Maxwell element
and relaxation spectra.
UNIT III 12
Fluid flow – types of fluid flow – time dependant fluids, shear rate dependant fluids,
Newtonian and Non Newtonian fluids – viscosity of polymer melts – shear thinning and
shear thickening – zero-shear rate viscosity – laminar flow of Newtonian fluids – power
law – general treatment of isothermal viscous flow in tubes – entrance and exit effects -
elastic effects in polymer melt flow - die- swell and melt fracture – Weissenberg effect –
normal stress difference – Elongational viscosity.
UNIT IV 12
Measurements of rheological properties – capillary rheometers – melt flow index – cone
and plate viscometer – torque rheometers – Mooney viscometer – curemeters – Rheooptical
methods – birefringence.
50
UNIT V 12
Rheological behaviour of important thermoplastics (PE,PVC,PS,PP,nylons and PC)-
Applications of rheology to polymer processing (injection moulding, extrusion and blow
moulding
TOTAL: 60 PERIODS
