Dynamic shear rheology

WebThe rheology of thermosetting res-ins can be studied using both steady shear and dynamic oscil-latory tests (sometimes referred to as dynamic mechanical analy-sis (DMA) or dynamic mechani-cal rheological testing ( DMRT). How steady shear, dynamic, and transient tests are run is de-scribed in a later section. Steady shear measurements can Webshear rate with stress is extremely small. The viscosity remains constant with increasing stress and is referred to as the zero shear viscosity. At a given stress, the material …
