Abstract

Numerical simulations were conducted on the penetration of different ideal segmented rods into steel targets by ANSYS/LS-DYNA3D. The Lagrangian method and Johnson-Cook constitutive model were coupled in the simulations. The effects of segment length and gap spacing on the depth of penetration were especially analyzed. The comparative analysis indicates that the length-diameter ratio and gap spacing of segments do not affect the depth of penetration monotonically increasing or decreasing, instead there exists an optimal parameter region.
