The behavior of material for velocities greater than 150 m/s can be considered as a direction for future research. were assigned. Fixed support gives restraint to the part to lower the degrees of freedom. The end time assigned for this simulation was 0.0004 seconds. The end time refers to the maximum duration, starting from time zero, that is considered for simulation in the explicit analysis. Explicit dynamic simulation with velocity taken as 150 m/s is shown (Fig. 8). The theoretical and experimental values of the velocities are 131.9 and 145 m/s, respectively, which are very close to each other. So, we considered the higher value of the velocity and rounded it off to the nearest convenient value for consistency and ease of analysis.

Fig. 8. Explicit Dynamics Simulation. After the explicit dynamic simulation, the total deformation of the composite was determined on ANSYS (Fig. 9.)

In the experimental testing, significant observations were made regarding the behaviour of the composite specimen under ballistic
