This is because the plastic is constantly expanding or stretching in those processes. Two polymers may have identical shear flow behavior, but they could exhibit different extensional flow behavior ...

Extensional structures provide some of the world's largest known oil reservoirs and remain one of the major frontier plays of the immediate future, both onshore and, particularly, in deep water ...

Researchers from NITech, Japan, have recently developed a novel full-field extensional rheo-optical technique that can accurately characterize structural deformations in a complex fluid under ...

Extensional flows dominate many polymer processes, including blow molding, film blowing, fiber spinning, thermoforming and many others. The rheology of polymeric materials under extensional flows can ...
