Abstract

Sandwich panels owing its high bending stiffness and low density are widely used in space and aerospace industry 1.Sandwich panel consists of two thin face sheet separated by the core material. Core geometry and material properties determine the strength and stiffness of the sandwich panel. In the aerospace industry, foam and metal cores are used. Honeycomb core is widely used in the satellite. In this paper, the impact resistance of metallic honeycomb is studied analytically. Analytical formulation discusses the resistance force,energy dissipation and damage in the metallic honeycomb. Analytical formulation discusses the perforation velocity of the projectile as function cell size and a wall thickness of honeycomb. The quasi-static test was done on various size of the honeycomb to study penetration and perforation by a spherical projectile. Analytical Formulation was compared with the impact experimental on metallic honeycomb by Goldsmith et al. 3, A.Alavi Nia et al. 4 and H.Zhao et al.5. Full 3D F.E model of the metallic honeycomb and projectile was developed in Abaqus 6.14 . Material and Geometric Nonlinearity has been modeled for the metallic honeycomb in the explicit simulation. Continuum damage modeling technique is used to compare the analytical, experimental and numerical results. © 2019 Elsevier Ltd. All rights reserved.
