Abstract
A multi-strand cord () having a 1×N structure comprises a single layer () of N strands () wound in a helix about a main axis (A), each strand () having one layer () of metal filaments (F) and comprising M>1 metal filaments wound in a helix about an axis (B). The cord () has a total elongation At>8.10% and the energy-at-break indicator Er of the cord (), defined by Er=∫σ(Ai)×dAi where σ(Ai) is the tensile stress in MPa measured at the elongation Ai and dAi is the elongation such that Er is strictly greater than 52 MJ/m.
