Tensile Strength

Name

Unit Symbol


Strength

Strength refers to the metal resistance 

ability of plastic deformation and fracture 

under external force.

Tensile Strength

σb

MPa

The tensile strength is the ratio of the maximum load metal specimen can 

withstand  before breaking and the original cross section area of specimen.

Pb

σb=——

Fo

Pb——Maximum load before specimen breaking(N)

Fo——Original cross sectional area of sample(mm )

 

Flexure Strength

Flexural Strength

σbb

MPa

The maximum positive pressure metal stand on the fractured section when the specimen is subjected to a concentrated load in the middle of the two supporting points and then break.

When the specimen is subjected to a concentrated load in the middle of the two support, the maximum positive pressure of the fractured section is broken when the fracture is broken

In the formula,  

P——Maximum concentrated load of specimen(N)
L——Span between two supporting points(mm)
d——Outer diameter of circular cross section specimen(mm)
b——Width of rectangular cross section specimen(mm)
h——Width of rectangular cross section specimen(mm)
