WebFundamentals of Rheology: 1 Introduction: Rheology deals with the flow of complex fluids. Fluids are different from solids, because fluids continuously deform when there is an applied stress, as shown in figure 1(b), while solids deform and then stop, as shown in figure 1(a). Solids are said to have an ‘elastic’ response, and can resist WebThe closing 4 minutes of my 29 lectures in Nonlinear Polymer Rheology. Presentation. Full-text available. Jan 2024; Shi-Qing Wang;
