WebAug 2, 2024 · According to Fig. 7, the samples prepared at 160 °C fully match the Bingham pseudoplastic model. Based on these results, the suitable temperature for injection of sample in the injection molding device is 160 °C, since the feed has Bingham pseudoplastic fluid behavior. WebIn Figure 7.8, μ a is the slope of the dashed lines in the rheograms for pseudoplastic, Bingham plastic, and Casson plastic fluids; for Newtonian fluids, μ a =μ. The apparent viscosity of a non-Newtonian fluid is not a physical property in the same way that Newtonian viscosity is: apparent viscosity depends on the shear force exerted on the ...

WebPseudoplasticity, or shear thinning, is a non-Newtonian behavior that is desirable for drilling fluids. Power-law and Herschel-Bulkley models describe pseudoplastic behavior, in which the slope—the viscosity—of the shear stress versus shear rate curve decreases as the shear rate decreases. WebAug 1, 2024 · The rheological properties of as-prepared ceramic pastes are similar to the Bingham plastic (fluid), which is a special type of non-Newtonian fluid, demonstrates a solid-like behavior under low shear stress and exhibits a non-linear shear-stress and shear-rate behavior after reaching the threshold value of shear stress, i.e., yield stress.
