Abstract
Assembly for energy absorption, comprising m number of substantially straight steel wires and n number of curved steel cords, at least one of the m number of substantially straight steel wires having a tensile strength of at least 1000 MPa and an elongation at fracture of at least 5%, at least one of the n number of curved steel cords having a tensile strength of at least 2000 MPa and an elongation at fracture of at least 2%, wherein m and n are integers m>1, n>1, and at least one of the m number of substantially straight steel wires and at least one of the n number of curved steel cords are fixed together along their longitudinal direction, and the elongation at fracture of at least one of the m number of substantially straight steel wires is at least 2% larger than the elongation at fracture of at least one of the n number of curved steel cords such that the elongation curve of the assembly comprises three zones ('), wherein a first zone (′) is characterized by an elastic deformation of the substantially straight steel wires, a second zone (′) is characterized by the plastic deformation of the substantially straight steel wires and a third zone (′) is composed of the continued plastic deformation of the substantially straight steel wires and the elastic deformation of the curved steel cords.
