The mathematics of myth: yield stress behavior as a limit of non-monotone constitutive theories. (English) Zbl 1274.76062
Summary: We formulate a model which can describe fluids with a non-monotone shear stress/shear rate relationship. It is shown how yield stress fluids arise as a limiting case of such a model. Differences between critical stresses for “fast” and “slow” yielding, hysteresis phenomena and thixotropy are naturally explained by the model.
