Abstract: A semi-analytical method is derived on the basis of Gurtin variational principle for solving one dimension initial-value problems of dynamics under alternating forces. This method takes finite element discretization in space domain and series in time domain.

Key words: semi-analytical method, initial-value problem of dynamics, bar, alternating force, dynamic response
