The contours in Figures 4 to 13 are visual representations of stress distribution within the model. In this specific section, an in-depth examination is carried out to screen the impact of ballistic projectiles on flat plate structures applied to oil tanker ships (Aranđelović et al., 2024; Prabowo et al., 2019a,b; Rossiter et al., 2010) . The subsequent analysis focuses on the results obtained from simulations that mainly simulate the von Mises stress distribution in aluminum material under ballistic impact conditions, with mesh varieties set to 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, and 1.5 mm. The point is to comprehensively understand how flat plane materials respond to ballistic impact and describe the stress distribution patterns (Ramírez- Gil et al., 2021; Dinulović et al., 2023; Krausz et al., 2023). This investigation contributes valuable knowledge towards improving fire safety considerations in designing and constructing plates as bunker walls for oil tanker ships.
