Penetration tests with scaled AP and MK-bomb models in layered structures
Abstract
A series of impact tests was carried out with 1 to 4.5 and 1 to 5.8 scaled inert AP and MK-bomb models against homogeneous and layered structures of concrete and sand targets. The subscale tests were performed to reduce the number of full-scale tests, to check the influence of several test parameters and the validity of scaled test results. The impact tests were carried out in the EMI proving ground impact range. The projectiles were launched from a 100 mm cal. smooth bore gun with sabots fabricated from hard styrofoam and polyethelene. In the test program, the following parameters were varied: type of projectiles, AP 2000 and MK84 scaled bomb models, the angle of incidence, 0 degree and 30 degree Nato, the target structure, reinforced concrete slab and layered structures of concrete and sand, and the impact velocity from 135 m/s to 240 m/s. The experimental results indicated a good agreement with the full-scale test.
