The constitutive equation of thixotropic fluid was of the Moore's
model in this paper. The mechanical behaviors under oscillatory loading
were discussed. The finite difference method was used.
The results show that: 1) In the steady state, the parameter which
described the internal structural state in the fluid was the periodic
function of time; 2) The relation between the stress and the strain was a
closed hysteretic cycle. These properties show that the thixotropic
fluid is much more complex than the other non-Newtonian fluids.
