Mechanical properties of steel plate
4. Sample stretching of steel plate
SS400 specimen tensile: during the tensile process, the material enters the strengthening stage after the yield stage, and the cross section size significantly decreases. The maximum force of destruction (Fb) divided by the original cross section of the specimen. The stress () derived from area (So) is called tensile strength or strength limit (b), in N/mm 2 (MPa). It represents the maximum resistance of a metal material to damage under tensile force. When yield reaches a certain level, resistance to deformation increases again due to rearrangement of internal particles. At this point, although the deformation develops rapidly, it can only increase with the increase of stress until the stress reaches the maximum. Since then, the resistance of the steel to deformation has decreased significantly, and the larger part of the specimen at the weakest point decreases rapidly, and the necking occurs until the fracture is destroyed. The maximum stress at which a steel is subjected to tensile fracture is called the strength limit or tensile strength.
