abstract = {In this paper, all simple Yetter-Drinfeld modules and indecomposable projective Yetter-Drinfeld modules over the    2-rank Taft algebra                      A        ¯             are construted and classified by Radford's method of constructing Yetter-Drinfeld modules over a Hopf algebra. Furthermore, the projective class ring of the category of Yetter-Drinfeld modules over                      A        ¯             is described explicitly by generators and relations.}
