Abstract

Impact analysis on structure is necessary in order to establish their use in
mechanical, military, and aerospace. The impact can applies in two main situations
direct and oblique. The purpose of this research is to study the response of the plate
are made fully seashell and seashell/CF for each if the different materials by compute
through Finite Element simulation software. This simulation will start with initial
velocity to find residual and ballistic limit velocity through finite element simulation.
Moreover, the study will observe damage behaviour and characteristic of oblique
impact. Besides that, the study of oblique impact between the bullet impact to fully
seashell plate and seashell/CF plate will conducted using the finite element method.
A flowchart already provide for better instructions and finding identification of the
problem to study simulation. Fully seashell have a larger ballistic limit than
seashell/CF. Energy required for hemispherical dace bullet to penetrate the fully
seashell plate is more than energy required for seashell/CF. From the data that, the
mode of failure and endpoint of boundary condition can be find. This study computed
the modelling of two different types of boundary conditions and mechanical
properties under oblique impact. The recommendation to more develop that the
results presented here can be compared and validation using both numerical and
experimental analysis.
