Abstract

In order to research the influences of the structure stress conditions to the impact damage of aircraft panel, based on the implicit to explicit sequential solution method of ANSYS/LS-DYNA program, the dynamic finite element simulation model of the aircraft panel with stress impacted by the projectile is created and calculated. The simulation results are got respectively with the different levels' tension, compression and without stress in the panel which is impacted by projectiles in high speed and the least speed. The impact response and damage of the panels are compared and the influences of the stress condition of the aircraft panel to the impact response are summed up. The results show that the compression stress can extend the panel's deformation and the tension stress can increase the impact damage hole size and area.

Key words： mechanics of explosion; impact damage; battle damage; aircraft panel; structure stress; finite element simulation
