アルミニウム合金板への尖頭薄板飛翔体の衝突・貫通現象

抄録

Experiments and simulations on sharp head projectile impact to circular plates made of aluminum alloy 2024-T3 were carried out. The crack limit velocity, perforation limit velocity and deformation of the plates were measured. These experimental results were compared with simulations using material properties experimentally obtained. The fracture mechanisms of impact point were discussed.
