Abstract:
An equivalent continuum model of an isog,rid structure is utilized to analyze the impact response of isogrid structures and stiffened structures. The parameters of the equivalent model are determined, and the comparison between the equivalent continuous structure and the real grid structure are examined to validate the reliability of the equivalent model. Then, the impact response of stiffened cylindrical shells with and. without an elliptical hole are investigated by using the equivalent model of grid structures. For a different location and geometry of the elliptical hole, the deformation and load-bearing capacity of the grid-stiffened cylindrical shells are studied. The numerical results indicate that the present equivalent model can be applied effectiyely in simulation for the impact behavior of the grid and stiffened structures. This work provides a comprehensive understanding for the impact performance, of the complicated stiffened cylindrical shells.
