Resumen: In different engineering applications such as automobile and train crashes, the high speed impact of debris as well as the high speed manufacturing processes, makes it necessary to have a deep understanding of the dynamic behavior of materials and components. There are different experimental techniques to determine the constitutive material behavior. Several constitutive models have been proposed to predict the dynamic response of engineering structures. However, in all cases, initial damage-free material is assumed and the structures are without fatigue damage when tested. The dynamic response of fatigue damaged AISI 1018 steel welded joints subjected to impact loading is investigated in this work. The tensile Hopkinson bar apparatus is used in the dynamic experiments. Welded joints without post weld heat treatment are used. Samples subjected to previous high cycle fatigue are considered. An investigation of the failure modes is performed as well. Results show that previous fatigue damage affects the quasi-static and dynamic tensile behavior. The effect of the previous fatigue damage on the quasi-static and dynamic tensile behavior on the base material and the welded joint is compared. Previous fatigue damage has a detrimental effect on ductility of 1018 steel welded joints, principally under dynamic loading.
