Abstract : A graphical-numerical method is developed for determining the response of nonlinear systems subjected to transient loads. The method consists of constructing phase-plane trajectories in conjunction with simple computations. The numerical equivalent procedure of the graphicalnumerical method is derived and a scaling law is presented for nonlinear multi-degree-of-freedom systems. Example problems are solved by the graphical-numerical method and the solutions compared with those of an analog computer at NRL. The solution of an example problem by both the graphical-numerical method and the numerical equivalent method indicates that the drawing error due to the graphical construction technique is negligible.
