Background technique

Metal mesh is a mesh structure made of metal materials (steel wire, iron wire and aluminum wire, etc.), and is mostly used for road blocking and animal fences. Tensile testing is required after the metal mesh is fabricated. Tensile strength is the critical value for the transition of metal from uniform plastic deformation to local concentrated plastic deformation, and is also the maximum bearing capacity of metal under static tensile conditions. Tensile strength is the resistance that characterizes the maximum uniform plastic deformation of the material. Before the tensile specimen is subjected to the maximum tensile stress, the deformation is uniform, but after it exceeds the maximum tensile stress, the metal begins to shrink, that is, concentrated deformation; for no (or small) brittle material with uniform plastic deformation, which reflects the fracture resistance of the material.
