Shear stress in non-cohesive solid-fluid mixture flow is due to impact among solid particles, viscous interaction between the solid and the fluid and turbulence in the interstitial fluid. Bagnold, based on analogy with the kinetic theory of gas, derived an equation for the shear stress due to...

Taking into account that the material changes its rheology and apparent viscosity according to magnetic field, a magnetically induced state transition is proposed; by the use of a state transition equation, a constitutive model for shear yield stress is defined, consisting of an expression that ...

1、流体力学(fluid mechanics)1., the factors relating to newton's law of internal friction are:a, pressure, velocity and viscosity; b, fluid viscosity, shear stress and angular deformation rate;c, shear stress, temperature, viscosity and velocity; d, pressure, viscosity and angular deformation....
To design magnetorheological devices and to predict how they work, one would need to find a specific relation between shear stress and shear rate in the magnetorheological fluid [30]. Behavior of MRFs in the absence of a magnetic field is very similar to the behavioral pattern of carrier fluid...

The fluid-structure interaction can be expressed by coupling the governing equation of the structure and fluid at the interface. The interface force caused by the fluid pressure at the interface is transferred to the structure. The structural equation of motion can be written as (Choi et al., ...
The pore pressure is controlled by the dilation of the pore space in the solid skeleton of the shear band during plastic deformation and by squeezing of pores in surrounding blocks by the dilating shear band due to the high stiffness of the host massif. A generalized equation has been derived...
