Abstract: This paper deals with solution of nonlinear dynamic problems using Pseudo-force method. A solution algorithm involving Pseudo-force method is presented. The objective is to investigate the possibility of application of the method to highly nonlinear dynamic problems to which the method has not been applied to by previous investigators, such as problems with combined material and geometric nonlinearities, and problems with frictional nonlinearities. It is shown that Pseudo-force method is applicable in the above mentioned dynamic problems, by comparing the results with analytical and experimental results.
