NET3D Calculation on the Depth of Penetration by a Long-Rod Penetrator with Varying Obliquity

Article Preview

Abstract:

The effect of the obliquity of a long-rod penetrator on the depth of penetration (DOP) into a witness block has been investigated by NET3D code based on a 3D finite element model with SK constitutive model and polynomial equation of state. The calculation results herein are in general agreement with limited number of experimental data and are very close to the calculation results of the CTH code, both of which are available in the literature. By combining with the present results with existing data, the DOP turns out to decrease rapidly with obliquity up to 30^o, decrease relatively slowly up to 70^o, and show a saturation behavior thereafter up to 90^o.
