The purpose of this study is to clarify the dynamic behavior of stress waves in strip plates with fillets experimentally. The reflection coefficient, with corresponds to the changes in the duration of the incident pulse and the fillet shape, has been obtained by the strain gauge method. The relationship between the duration of incident stress waves to the fillet and the dynamic stress concentration factor is obtained by a dynamic photoelastic method. An interaction of the incident wave and the reflected wave takes place at the fillet. Depending on the fillet shape, the dynamic stress concentration factor becomes 10-70% higher than the static stress concentration factor for incident waves. The relationship between the duration of stress pulse and the dynamic stress concentration factor has also been obtained.
