The discrete singular convolution (DSC) was introduced for analyzing the dynamical responses of materially nonlinear pole.The discrete singular convolution (DSC) is a new numerical method,which has not only the high accuracy of global methods but also the flexibility of local methods.The discrete singular convolution (DSC)algorithm was adopted to discretize the spatial derivatives,while the fourthorder Runge-Kutta method was adopted to discretize the temporal derivatives.The DSC results were very consistent with the solutions obtained by the perturbation method.It indicates that the discrete singular convolution is a very efficient,robust numerical method with high accuracy for solving the responses of materially nonlinear structures.
