Element Simulation

The finite-element simulation models of the projectile and the discrete rod impacting to the aircraft panel structure in high velocity are established according to some experiment projects. Based on dynamic finite-element Program, the forming of impact damage in the panel structure is simulated. Through comparing the simulation results of damage pattern and size in the panel to the experiment results, the reliability of the material models and equations of state and contact algorithm used in the simulations is testified. Take the simulation of projectile vertically impacting to the panel as example, the aircraft panel structure response characteristics are analyzed briefly based on the results including the displacement of typical node in the panel, the stress course of one element and the energy change of the panel.

The effect of low velocity impact response on the thin laminated composite cylindrical shell with different stacking sequences was investigated. Finite element simulation using ABAQUS software was the base of the study during the analysis. The framework was to study the stress and displacement in radial and circumferential directions through finite element simulation. For simplicity, an arbitrarily picked circumferential path at where the impactor impacts the shell surface was selected. The graphs plotted based on stress and displacement variables Vs radial and circumferential directions did not show the significant changes for laminations with different stacking sequences. In addition, The 90 degree along circumferential and radial directions was found to be the critical point.
