Throughout of humanity history, war conflicts have been a constant. Since the Upper Paleolithic, the weapons development used in combat has given rise, almost jointly, to the development and expansion of cities where fortifications prevailed as an emblematic building. It is precisely in the Age of Metals, where the development of swords significantly fueled conflicts, with the falcata being one of the main bladed weapons associated with the populations of the southeast of Iberian Peninsula in pre-Roman times. In this research work, all falcata sections, 12 in total, found in archaeological sites, were modeled. Each sword was then subjected to finite element stress analysis to determine its suitability in combat. The results show that the displacement vs weight relationship is important in deciding whether the sword was used in the initial training of soldiers or in real combat. On the other hand, the excessive tension exerted, during combat, on the tip of each of the sword sections analyzed, suggests that its design made it easy for it to be lost in hand-to-hand combat. In conclusion, the design of each section was of great importance for its effective use in combat, probably due to a strategic decision related to the enemy to be faced.
