The Influence of Target Mesh on the Simulation Results of High Velocity Projectile Penetration

Abstract:

In the simulation, the mesh quality has a significant impact on the simulation results. To study the influence of the size and shape of target mesh on the high velocity projectile penetration into concrete, using ANSYS/LS-DYNA software in this paper, different target mesh side lengths are selected to simulate, the variation curve that depth of penetration (DOP) with target mesh side length is obtained, select 1/6 times projectile radius as the target mesh side length can meet the accuracy requirements. Based the target mesh side length above, different radios of the mesh side length in the radial direction to the side length in the axial direction are selected to simulate, the influence law of calculating results that depend on the mesh shape is acquired. The contrast validation of experimental results is carried out, the simulation results are in agreement with the experimental results.
