Abstract. Ballistic tests were carried out using carbon/epoxy composite panels and
standard ball munitions. Impact and residual velocities of the projectiles
and damage area, including delamination, of the test panels were
measured. FATEPEN prediction and Dyna3D simulation were conducted. Residual velocities
and hole areas predicted by FATEPEN are comparable to, but
do not accurately agree with, the measured residual velocities and
the visible damage areas on the specimens. Residual velocities predicted
by Dyna3D are closer to the measured velocities. Similar to
the FATEPEN prediction, hole areas predicted by Dyna3D are comparable
to the visible damage areas on the specimens. Delamination areas
predicted by Dyna3D appear to agree with the measurement reasonably
well. Hence Dyna3D appears to be a useful tool for
evaluation of delamination and thus structure residual strength of composite
panels after ballistic impact.
