FLUIDS HAVING A CONTROLLED STRESS RESPONSE CHARACTERISTIC

摘要

A shear thickening fluid having a controlled stress response, in which various stress response characteristics, including, an onset stress, a boundary stress and a fractures stress, can be controlled. The stress response characteristics controlled by the controlled properties of the shear thickening fluid, including the viscosity of a fluid medium, the mechanical properties of the suspended particles and the mechanical properties of the fluid boundary.

1. A shear thickening fluid having a controlled stress response, the controlled stress response having a controllable onset stress at which an onset viscosity of the shear thickening fluid begins to increase in response to an applied shear stress and a controllable boundary stress at which a boundary viscosity of the shear thickening fluid reaches a maximum viscosity in response to the applied shear stress, the shear thickening fluid, comprising:
a fluid medium having a fluid medium characteristic; a plurality of particles suspended in the fluid medium, the plurality of particles having a particles characteristic; a boundary enclosing the fluid suspended in the fluid medium, the boundary having a boundary characteristic; wherein at least one of the fluid medium characteristic, the particles characteristic and the boundary characteristic are selected based on at least one of a preselected magnitude of the controllable onset stress and a preselected magnitude of the controllable boundary stress of the shear thickening fluid.
