Comment on "Universal yield stress equation for transient response of zeolite based electrorheological fluid".
We comment on the transient process of an electrorheological (ER) fluid under square-wave electric field excitation by analyzing its electric field-induced stable shear stress at a different shear rate. Using a critical electric field in the ER system, we find that the universal yield stress equation collapses the reported experimental data onto a single curve very well.
