A rocker assembly, or an elongated beam, for a vehicle that includes an outer panel, a side sill and an insert disposed in a cavity. The insert includes a plurality of layers of reinforcements made up of hexagonal cells having interconnected walls defining a plurality of transversely extending open cells that define openings extending perpendicularly relative to the length of the rocker assembly. The plurality of layers of reinforcements may further comprise a first layer of cells assembled to the outer panel, a second layer of cells assembled to the side sill and a third layer of cells disposed between the first and second layers of cells. A wall thickness and bending strength of one of the plurality of layers of reinforcements is different than a wall thickness and bending strength of another of the plurality of layers of reinforcements. The insert is structured to deform progressively.
