| Abstract: | This paper researches the strut with hole subjected to an axial impact loading to reduce the dynamic stress concentration by means of dynamic photoelasticity and finite element method. It was shown that the dynamic stress concentration factor (DSCF) K_d of the main hole can be reduced by introducing an auxiliary hole under the main hole. The variation of the DSCF with the size of the auxiliary hole had been found and simultaneously the optimum size of the auxiliary hole was obtained. |
