A penalty function is used to satisfy a weak continuity of the displacement in HPM. In the iterative method such as the step by step integration for dynamic problems, the influence of the penalty function to numerical solution is not studied enough. In this paper, formulation of HPM for the dynamic problem with the implicit method using Newmark's β method is shown and the accuracy of the solution is verified by numerical example. In the two-dimensional problems, the solution which is the same as FEM is obtained, and a similar result is obtained in a beam theory. According to the implicit method, a solution of same accuracy as FEM is obtained in the dynamic analysis in HPM using a penalty function.
