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.
