2. Materials: volume and surface properties
2.1 Volume properties of materials
The method of manufacturing a thin sheet for bodywork is described on 4. These are very low-carbon steel sheets (yield strength Re ~ 160 to 200 MPa) whose high formability is ensured by the high value of their elongation at breakA (∼ 35 to 45%) and their normal anisotropy coefficienter (∼ 1.7 to 1.85) (1). For a definition of the normal anisotropy coefficient, please refer to
