In summary, Pseudo-plastic fluids are non-Newtonian fluids that become easier to flow with increasing shear rate, while Bingham plastic fluids have a constant viscosity at low shear rates and then behave like a Newtonian fluid at higher shear rates. Some common examples of Pseudo-plastic fluids include ketchup, toothpaste, and blood, while examples of Bingham plastic fluids include mayonnaise, peanut butter, and clay.

The title says it all what are the differences between Pseudo-plastic and Bingham plastic?

Im just studying about this topic as well

so I think the difference is that Bingham is one of rheological model and a time independent behavior for low MW polymers where as pseudoplastic is one of power-law behavior where n<1 or it also known as shear rate thinning since viscosity decreases with increase in shear rate. So both of them are just two different models I guess although they have the same behavior in the case of viscosity and shear rate. Hope this helps. Cheers
 

What is a Pseudo-plastic fluid?

A pseudo-plastic fluid is a type of non-Newtonian fluid that exhibits a decrease in viscosity with increasing shear rate. This means that as the fluid is subjected to more force or stress, it flows more easily.

What is a Bingham plastic fluid?

A Bingham plastic fluid is also a type of non-Newtonian fluid, but it exhibits a constant viscosity at low shear rates and then behaves like a Newtonian fluid at higher shear rates. This means that the fluid only starts to flow once a certain amount of force or stress is applied.

What are the main differences between Pseudo-plastic and Bingham plastic?

The main difference between these two types of fluids is how they respond to shear stress. Pseudo-plastic fluids decrease in viscosity with increasing shear rate, while Bingham plastic fluids have a constant viscosity at low shear rates and then behave like a Newtonian fluid at higher shear rates.

What are some examples of Pseudo-plastic fluids?

Some common examples of Pseudo-plastic fluids include ketchup, toothpaste, and blood. These fluids exhibit a decrease in viscosity when subjected to shear stress, making them easier to pour, spread, or flow.

What are some examples of Bingham plastic fluids?

Examples of Bingham plastic fluids include mayonnaise, peanut butter, and clay. These fluids have a constant viscosity at low shear rates, but once a certain amount of force is applied, they start to flow like a Newtonian fluid.
