Investigation of the High Velocity Impact Test on the Curved Glass Fiber Reinforced Plastic (GFRP) Composites Using Explicit Dynamics Analysis

In this study, investigation of the high-Velocity Impact test on the curved glass fiber reinforced plastic (GFRP) composites using explicit dynamics analysis has been performed using FEM. Four types of energy were examined: internal energy, kinetic energy, contact energy, and hourglass energy. The investigation revealed that the most significant variation occurred in the internal energy, reaching a peak value of 1.0e-3. Deformation due to impacted forces was considered accordingly. Three forces were considered accordingly: 1,2,3 kn. Based on the numerical analysis, the maximum deformation was reached 76 mm. Von Mises stress due to the applied load was considered as well. The von Mises stresses using explicit dynamic tools in analysis software. Three loads were considered for the general inspections till 3 KN. The numerical results proved that the maximum stress reached 22 MPa. This substantial change is primarily due to the alterations in the material’s morphology, indicating how the material's internal structure responded to the applied conditions. Kinetic energy, which relates to the motion of the material, and contact energy, which pertains to the interactions at the material’s surfaces, were also analyzed. However, these energies did not exhibit as pronounced changes as the internal energy.
