Reducing hemolysis has been one of the major goals of rotary blood pump development and in the investigational phase, the capability of hemolysis estimation for areas of elevated shear stresses is valuable. The degree of hemolysis is determined by the amplitude of shear stress and the exposure time, but to date, the exact hemolytic behavior at elevated shear stresses and potential thresholds fo...

We consider the adiabatic shearing of an incompressible non-Newtonian liquid with temperature dependent viscosity, subjected to steady shearing of the boundary. Identical equations govern the plastic shearing of a solid exhibiting thermal softening and strain rate sensitivity with constitutive relation obeying a certain power law. We establish that every classical solution approaches a uniform ...

1. A modified falling ball viscometer (rolling ball viscometer) for blood and other humors is presented. It is capable of easily measuring flow properties at several stresses, as is required to define satisfactorily the properties of anomalous flow systems. At high shearing stresses, apparent specific viscosity values of 2.5 + are observed, corresponding to 2.2 +/-0.2 reported as possible with ...

Mechanical properties of hydrate-bearing sediments (HBS) are crucial for evaluating drilling- and production-induced geo-hazards. However, investigations on mechanical behaviors clayey-silt samples containing hydrate insufficient due to low efficiency in preparing reconstituted samples. Herein, we carried out a series triaxial shear tests analyze the deformation tetrahydrofuran (THF) hydrate. T...

The stability of the interface between mortar and rock is very important in engineering construction. In this paper, all-digital acoustic emission (AE) system used to detect direct shear test mortar-rock binary medium with different sawtooth angles under normal stress states. stress-displacement information AE signal during whole shearing process are extracted. coupling relationship characteris...
