Abstract: The work focuses on impact analysis of SS 304 spherical fragments on Steel 1006 target plate. The objective of the study is to analyze the effect of fragment mass, impact velocity and obliquity angle on behaviour and damage mechanism when SS 304 spherical fragments, impact a Steel 1006 target. The lethality of impact is evaluated by analyzing the target volume erosion, projectile volume erosion and residual velocity of the fragments after impact. The FE model is made in LS DYNA, using Johnson-Cook strength and damage model coupled with Gruneisen EOS and erosion surface to surface contact to simulate the impact scenario. The results are useful for designing protective structures against fragmented projectiles and for assessing the vulnerability of structural components to impact events.
