The present paper very briefly outlines the so-called Dynamic Relaxation Method (DRM)which is found to be suitable in analysis of both geometrical and material nonlinearities using personal computers, and discuss an approach recently at SWJT for the automatic selection of interaction parameters in the DRM. The solution of a nonlinear truss-spring, the analysis of plate bending problems with large deflections under transverse loading, and the calculation of the ultimate load of plates under an in-plane load, using DRM with personal computers, are described.
