PRINCIPLES OFRHEOLOGYAND ITSMEASUREMENTTECHNIQUESViscosity – Elasticity –ViscoelasticityOctober 17–18, 2016Malmö – SwedenViscometryThe flow behaviour of different liquids is presented:Time Independent liquids, such as Newtonian, shearthinning, shear thickening and yield stress and TimeDependent liquids, such as thixotropic, rheopectic andantithixotropic. The flow behaviours are presented indifferent linear and logarithmic viscosity and flow diagrams.Rheometry, that is the practical application of rheology,is discussed in relation to the different flow behaviours.For instance different measurement techniques mustbe applied to differentiate between shear thinning andthixotropic flow behaviour. Measurement data are fitted to different flow models such as the Power Law,Bingham, Herschel Bulkley and the Casson to simplifythe presentation of rheological measurement data overa wide shear rate range.Linear viscoelasticity, Part I and IIThis course is held for the 23 time and it hasbeen updated continuously.rdCourse outlineAn introduction to rheologyA general presentation of the science of rheology andits application in different industrial branches. Concepts like liquids, solids, viscosity, elasticity, viscoelasticity and the Deborah number will be explained.Basic rheological conceptsThe most important concepts of rheology are defined:shear stress, shear rate, strain, viscosity, elasticity andextensional viscosity. Parameters influencing the magnitude of these concepts will also be introduced. Theviscosity of some known liquids is given as well as theshear rate of different industrial processes.Experimental rheological techniquesFundamental and empirical rheological measurementtechniques are presented and the corresponding application of the measurement results in material characterization is discussed. It is shown that empiricalmeasurement results only can be used for comparativereasons where as fundamental results can be used forcalculations of different material properties.Empirical and fundamental rheological instruments arealso discussed and displayed. Similarities and differences between controlled strain and controlled stressmeasurements will be explained.Linear viscoelasticity is defined both practically andtheoretically. It is explained how linear visco elasticmeasurements correspond to the degree of structureof a material. Viscoelastic concepts such as complexmodulus, storage modulus, loss modulus, relaxationmodulus, phase angle, dynamic viscosity, creep compliance and complex viscosity are defined and a mathematical approach to the relation between the differentconcepts is given. Concepts like stress and strain tensors are introduced.Rheological measurements in simple shear mode andsimple mechanical models like the spring and the dashpot are introduced to simplify the interpretation ofrheological measurement data. Viscoelastic flow models such as the Maxwell and the Kelvin models areintroduced. In viscoelasticity, these models are the linkbetween theoretical and practical rheological flow anddeformation behaviour. Linear viscoelastic measurement methods are presented, such as oscillation, relaxation and creep and the measurement methods areillustrated by several worked examples.Rheometry: General rheologicalmeasuring methods and interpretation ofrheological measurement resultsA practical and useful guide is given, based on workedexamples, to successful applied measurements in viscometry, frequency sweep, strain sweep, stress sweep,creep and relaxation. The corresponding measurementresults are interpreted to relate rheological parametersto material properties.CALMIA AB · Apelgatan 7 · 223 59 Lund · Sweden · Tel: 46-(0)46 211 00 20 · calmia@calmia.se · www.calmia.se

Advice is given on appropriate measuring geometriesfor different materials, like cone/plate, plate/plate andconcentric cylinders. Rheological measuring techniques for studying material properties are defined suchas consistency, storage stability, process viscosity,mouth feel, sagging, levelling, hardening, molecularweight and gel strength.Course descriptionThis course is a combined English version of the muchappreciated courses ‘Basic Rheology’ and ‘AdvancedRheology’. The courses have been held every year inSwedish since 1992 and hundreds of persons from theNordic countries have attended.The English version has until now attracted scientistsfrom all over the world.Rheology is the science of flow and deformation ofmaterials. The viscosity of a material is related to itsresistance to flow while the elasticity is related to itsdegree of structure. To determine the consistency ofa material both its viscosity and elasticity parametersmust be studied.The rheological properties of a material are determinedby the temperature, the pressure and the strain or theshear rate. Knowing the magnitude of these parametersin industrial processes the viscous and the elastic properties of a material can be studied in a laboratory environment by using fundamental rheological instrumentssuch as rheometers.The measurement results can be used to study differentmaterial properties such as consistency, storage stability, melting temperature, hardening temperature, shearstability and molecular weight. It can also be used tooptimise product quality and to predict the impact of anindustrial process on a specific product formulation.The objective of this course is to give the participants abasic knowledge in both theoretical and applied rheology as well as in rheological instrumentation and thecorresponding measurement techniques.Course lecturerAnnika Sahlström, MScis a Rheology Consultant at Reokonsa AB.Prior to her current employment she was theInnovation Director at Cloetta AB.After her graduation in chemical engineering atLund Technical University she joined Bohlin Instruments AB in Lund, a company involved in developing and marketing rheological instrumentation. In this employment she gained vast experienceof various applications and different rheologicalproblems, and acquired a broad knowledge of rheological measuring techniques and the handling ofinstrumentation. She was involved in the trainingand teaching of personnel world wide.Prior to her current employment she has workedat Tetra Pak AB where she was engaged in processdesign related to factory installation of processingand filling equipment and in packaging material development and analysis. During her employment atNestlé R & D Center in Bjuv AB she was involvedin project management of product and process development as well as engineering of new products.Parallel with her employment, she has been engaged by Calmia AB since 1992 to lecture at coursesin rheology at different levels.Annika Sahlström was honoured in 1997 with‘The Rheology Award of the Year’ by The NordicRheology Society for her skill in teaching rheology.CALMIA AB · Apelgatan 7 · 223 59 Lund · Sweden · Tel: 46-(0)46 211 00 20 · calmia@calmia.se · www.calmia.se
