Damage Effect of Titanium Alloy by Reactive Fragment Oblique Penetration

The damage effect of reactive fragments on titanium alloy plates is studied through experiment and theoretical analysis. The oblique penetration process and the damage effects of the target influenced by the incident angle and velocity were analyzed. The results show that: Under the condition of 30° incidence angle, the perforation formation modes are extrusion and warping/tearing at 734m/s and 704m/s, respectively, which result to the perforation dimension at 704m/s is 1.56 times of 734m/s; The bulge is formed under the velocity of 1040m/s, at 60° and the reaction ratio of reactive fragments is insufficient. According to the damage morphology of the plate, the damage area in front of the plate can be described as five regions, and the energy density effect on the plate decreases with the increase of the incident Angle.
