In this research, firstly, the first to fourth generation tanks of cars was modeled and each of them was compared in terms of weight. The designed tanks were then tested at 200 bar hydrostatic pressure using the criterion of Tsai-Hill failure in the ABAQUS software to confirm the design accuracy and strength. Finally, the amount of damage to tanks under impact loading with different velocities and angles was investigated. The behavior of tanks was analyzed with the help of metal and composite damage criteria to determine the most appropriate type of tank to identify equal damage caused by impact. Simulations of damage to the metal part of the tanks evaluated using the Johnson-Cook criteria and the damage of composite part of the tanks evaluated using the Hashin criteria. The results of this research showed that the fourth generation tank shows much better performance in vertical and horizontal collisions at speeds of 30 and 60 km/hr. Also, compared to other generations, it has much less weight and is about 47% lighter compared to the first generation.
