Web18 Jul 2024 · A shock wave front is a stress or free surface velocity history profile along the impact loading direction that can macroscopically reflect the mechanical response of a metallic material during the impact compression phase . The shock wave front is an abrupt surface with a certain transition zone. WebHence, the vessel-impact responses of bridges may be significantly underestimated and the structural safety cannot be warranted in practice. In this paper, a simple procedure is proposed to define the dynamic ship-impact loads on bridge structures. Firstly, the equations to determine the duration of loading and the maximum ship-bow crush depth ...
