The calculation formula of steel plate bearing capacity is σ= Fb/So

in the tensile process, the steel plate enters the strengthening stage after the yielding stage, and then the maximum force (FB) is obtained by dividing the original cross-sectional area (so) of the sample with the obvious rection of the transverse section size σ， It is called tensile strength or strength limit σ b) The unit is n / (MPA)

it indicates the maximum ability of metal material to resist failure under tensile force. The calculation formula is as follows: σ= Fb/So

extended data:

when the steel yield to a certain extent, e to the rearrangement of internal grains, its resistance to deformation is improved again. At this time, although the deformation develops rapidly, it can only be improved with the increase of stress

the ability of steel to resist deformation is obviously reced, and a large plastic deformation occurs at the weakest point, where the cross section shrinks rapidly, necking phenomenon appears, until fracture failure. Unit: n / mm ^ 2 (kilogram force per unit area)

in China, the universal material testing machine is widely used to measure the tensile / compressive strength of materials

for brittle materials and plastic materials without necking, the highest tensile load is the fracture load, so the tensile strength also represents the fracture resistance. For necking plastic materials, the tensile strength represents the resistance to the maximum uniform deformation and the ultimate bearing capacity of the material under static tension

for parts such as wire rope, tensile strength is a significant performance index. Tensile strength is easy to measure and has good reprocibility. It has a certain relationship with other mechanical properties such as fatigue limit and hardness. Therefore, it is also used as one of the conventional mechanical properties to evaluate proct quality and process specification
