Rotorcraft, especially in military applications, can experience damage during regular operation. In this work the ballistic damage tolerance capability of aluminum and composite drive shaft segment with and without damage at different locations are carried out for various boundary conditions to determine strength, stiffness using finite element modeling. Rapid technological advances in engineering brought the scientists and engineers to a point, where they became limited by the capabilities of traditional materials. With the limits of the technology pushed, the materials failed to answer the requirements of the designers or manufacturers. Researchers in materials technology are constantly looking for solutions to provide stronger, durable materials which will answer the needs of their fellow engineers. Composite materials are one of the most favored solutions to this problem in the field.
