Perforation under hyper velocity impact - A prediction using finite element technique
(2005) Suhas, M.; Samgeeth, R.; Veenaranjini, S.M.; Singh, G.
The objective of the present study is to predict analytically the material perforation under hyper velocity impact. Hyper velocity impact is a complex phenomenon involving wave propagation, penetration and responses exceeding elastic limits, leading to hydrodynamic behaviour. A general-purpose program (GPP) that permits a combination of non-linear finite element technique and explicit integration scheme, is employed for the simulations. The geometry of perforation is computed for various projectiles with different incident angles, impact velocities and materials. The computed values are compared with test results available in the literature. The results indicate excellent agreement with the measurements and give good insight into the effect of various parameters on the perforation size and geometry.
