Abstract

This study uses numerical modeling to explore the intricate relationship between low-velocity impact and composite materials. The study investigates the impact response of composite materials under low-speed loading circumstances in great detail. Two specimens were prepared for the current study the first one has a uniform thickness for each layer, and the second is prepared with altering layer thicknesses. A tensile test was employed to obtain the mechanical properties to use it in the numerical analysis. An impact test was employed in this analysis, where the impactor was modeled also on a height of 300 mm, the analysis time was taken as 0.08 s to capture all the impact. The numerical analysis was verified with other studies, and the error percentage did not exceed 2%. The results showed that the second specimen with alternating thickness had the best behavior.
