Plate armour represents a highly engineered protective technology constructed from multiple plates of treated metal, such as steel. The design principles focus on maximizing resistance to kinetic energy and bladed impact while maintaining a degree of mobility for the wearer. Structurally, the armor utilizes overlapping plates connected by riveting or articulated joints, forming a composite system that distributes force across the body's contours. Functionally, the effectiveness of the armor depends heavily on the metallurgical properties of the constituent materials, requiring controlled hardness, tensile strength, and flexibility. The sophisticated articulation of the plates is a key technological achievement, allowing the wearer to move through various ranges of motion without compromising the integrity of the protective shell.
