Abstract
A multi-strand cord () comprises an internal layer (CI) made up of K=1 internal strand (TI) having two layers (C, C), with the internal layer (C) being made up of Q internal metallic threads (F) and the external layer (C) being made up of N external metallic threads (F), and an external layer (CE) made up of L>1 external strands (TE) having two layers (C', C′) wound around the internal layer (CI), with the internal layer (C′) being made up of Q′ internal metallic threads (F′) and the external layer (C′) being made up of N′ external metallic threads (F′). The cord () has an energy-to-break per unit area ES≥145 N·mmwith where is the sum of the forces at break, is the sum of the total elongation, Cfrag is the coefficient of weakening, and D is the diameter.
