摘要：

This paper examines the validity of modification equations of Gauss sampling points in the analysis of specific damping capacity. In the mean time, the damping matrix used in the evaluation of specific damping capacity is symmetrized with the conventional asymmetric damping matrix. In addition, the validity of a modification equation of Gauss sampling points in the analysis of undamped/damped forced motion of a composite plate is also examined. In this case, the theoretical errors of the undamped/damped forced motion of a composite plate are predicted from the reduction in the order of numerical integration.
