Mild steel plates impacted by hard projectiless to missile
What is it about?
Experiments on penetration of 23 mm hard projectiles into mild steel plates were performed for 500 mm square plates with 30, 50, 60, and 150 mm total thicknesses. Results for ballistic limits obtained from existing empirical and analytical relations are compared with those from experiments. In addition, numerical simulations to predict the experimental results were made. Erosion (cell removal) criteria were established in order to realize simulation. Effect of the erosion strain value for which cells are removed on the prediction of penetration into steel plates was investigated.
Why is it important?
The numerical results show that erosion strain value has a significant effect on the prediction of perforation into steel plates.
