Abstract In order to study the influence of different spherical fragments on penetration depth concrete targets, AUTODYN-2D software is used model and simulate with diameters, materials velocities. Through analysis data, it found that tungsten alloy will not continue increase at higher speeds (when v > 1400 m / s, begins decrease). The process fragment penetrating analyzed, relationship betw...

An attempt is made to generate effective atomic number, exposure buildup factor (EBF) in the energy region 0.015-15.0 MeV up to a penetration depth of 40 mfp for some soils. The five parameters geometrical progression (G-P) fitting approximation has been used to calculate exposure build-up factor (EBF). The generated exposure buildup factors has been studied as function of incident photon energ...

We present an incremental algorithm to estimate the penetration depth between convex polytopes in 3D. The algorithm incrementally seeks a “locally optimal solution” by walking on the surface of the Minkowski sums. The surface of the Minkowski sums is computed implicitly by constructing a local Gauss map. In practice, the algorithm works well when there is high motion coherence in the environmen...
