Abstract

A gas-actuated penetration device has been developed for high-energy impact testing of structures. The high-energy impact testing is for experimental simulation of uncontained engine failures. The non-linear transient finite element code LS-DYNA3D has been used in the numerical simulations of a titanium rectangular blade with an aluminum target plate. Threshold velocities for different combinations of pitch and yaw angles of the impactor were obtained for the impactor-target test configuration in the numerical simulations. Complete penetration of the target plate was also simulated numerically. Finally, limited comparison of analytical and experimental results is presented for complete penetration of the target by the impactor.
