چکیده انگلیسی
⺠High stress/strain rate squeezing flow behavior of a concentrated colloidal suspension is evaluated via Hopkinson bar methodology. ⺠Results provide insight into the transitional and post-transitional behavior of these discontinuously thickening materials under compressive loading. ⺠A phenomenological model describing the overall material response is achieved via surface fitting Ï-ε-ÎµË plots of experimental results. ⺠Analysis of the model reveals that, after an initial period of viscous deformation, the suspension behavior is viscoelastic. ⺠At high stresses, the suspension exhibits purely viscous behavior, consistent with current elastohydrodynamic models.
