Basic Course
Kinexus Rheometer

Language: English - Duration: 178 Min.

This course introduces fundamental rheology concepts and provides guidance on selecting geometries, cartridges, and accessories for Kinexus rheometers. It covers key measurement techniques including viscosity tests, Yield StressYield stress is defined as the stress below which no flow occurs; literally behaves like a weak solid at rest and a liquid when yielded.yield stress, viscoelasticity, amplitude and frequency sweeps, oscillatory vs. rotational methods, CreepCreep describes a time and temperature dependent plastic deformation under a constant force. When a constant force is applied to a rubber compound, the initial deformation obtained due to the application of the force is not fixed. The deformation will increase with time.creep and recovery, and StressStress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area). Samples having a circular or rectangular cross section can be compressed or stretched. Elastic materials like rubber can be stretched up to 5 to 10 times their original length.stress RelaxationWhen a constant strain is applied to a rubber compound, the force necessary to maintain that strain is not constant but decreases with time; this behavior is known as stress relaxation. The process responsible for stress relaxation can be physical or chemical, and under normal conditions, both will occur at the same time. relaxation. Participants gain a comprehensive foundation for performing and interpreting Kinexus rheological measurements.
