The investigations on the transient phenomena of vibration of a strut due to axial impact load are scarcely known so far as the author is aware, and only the case of the strut under constant impact load is mathematically investigated. In the previous papers the author explaned influence of the initial condition of vibrating strut upon the transient vibration and the case of buckling of the straight bar due to axial impact load. The present writer deals with, as the third report, the case of transient vibration of the strut having initial deformation same as fundamental mode of vibration under axial impact load. In the results of the present investigation, the author has been proposed a convenient solid curve to find the amplitude of the transient vibration in connection with the given magnitude of impact load and the duration of impact. The model experiments which already explaned in the previous first paper were carried out and compared with results of theoretical calculations.
