    Abstract

    The stationary, shear rate dependent flow curves of yielding glasses are discussed within a mode coupling theory approach. Asymptotic formulae for the shear stress at the transition point are obtained that take the form of generalized Hershel-Bulkeley constitutive equations, and enable one to find dynamical yield stresses by extrapolation.
