The following sections will be covered during this session:
- Introduction
- What is rheology?
- What are structured fluids and viscoelastic materials?
- The Rheologist’s Toolkit of Parameters: Identifying the information critical to your products and processes
- Structure Parameters:
- Phase Angle
- Complex Modulus
- Elastic and Viscous Moduli
- Compliance
- Zero-shear Viscosity
- Yield / Recovery Parameters:
- Yield Stress
- Yield Strain
- Thixotropic Breakdown Rate
- Thixotropic Recovery Rate
- Flow Parameters:
- Viscosity at Relevant Shear Rate
- Infinite Shear Viscosity
- Viscosity-profile Parameters
- Understanding viscoelasticity and the concept of elasticity in liquids
- Definition of "solidity" / elasticity
- How to measure "solidity": the oscillation technique
- Viscoelastic parameters explained
- Comparing food products: Hotdog mustard vs cream cheese
- Comparing topical products of varying “stiffness”: Ointment, lotion & cream
- Viscoelasticity and timescale
- Back to the Rheologist’s Toolkit: what have we learnt?
- 30 mins QnA - directly answered by the expert
- For more questions, email us up to 3 days from the course
The concepts will be presented in an accessible style, without the fearsome equations that often dominate the published literature on the subject.
