Abstract

Abstract

The present paper conducts a numerical study on the dynamic plastic buckling of deep penetrating projectiles. Numerical simulations display the different processes of failure and destruction of projectiles with LS-DYNA3D. It confirms that, two failure modes, i.e., crapy buckling and dynamic expansion buckling exist for different length-diameter-ratio projectiles, which have observed in the experimental study. Characteristic acceleration curves correspond to different modes of buckling failure. Two kinetic fields of rigid-plastic three-hinges are constructed to describe the two modes of buckling failure.
