SUMMARY

The discussion clarifies the differences between Pseudo-plastic and Bingham plastic materials. Bingham plastic is identified as a rheological model exhibiting time-independent behavior, particularly for low molecular weight (MW) polymers. In contrast, Pseudo-plastic materials demonstrate power-law behavior characterized by shear rate thinning, where viscosity decreases as shear rate increases. Both models illustrate distinct yet related behaviors concerning viscosity and shear rate.

PREREQUISITES
  • Understanding of rheological models
  • Knowledge of polymer science, specifically low molecular weight polymers
  • Familiarity with shear rate and viscosity concepts
  • Basic principles of fluid mechanics
NEXT STEPS
  • Research Bingham plastic models in detail
  • Explore Pseudo-plastic behavior and its applications in materials science
  • Study the implications of shear rate thinning in industrial processes
  • Investigate the role of molecular weight in polymer rheology
USEFUL FOR

Students and professionals in materials science, chemical engineering, and polymer technology who are looking to deepen their understanding of rheological behaviors in various materials.

The title says it all what are the differences between Pseudo-plastic and Bingham plastic?
 
Engineering news on Phys.org
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
