The geometrical quantum discord (GQD) is an effective measure of quantum correlation in quantum systems. We investigate the dynamics of quantum correlation between two atoms in a damping Jaynes-Cummings (J-C) model according to the geometrical quantum discord. The evolutional characteristics of GQD are given for both the resonant and non-resonant cases; moreover, the effect of damping on GQD is revealed.
