"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 " - Polymer rheology lecture
