409 stainless steel plate stretching problem

How to measure the elongation of 409 stainless steel plate?

Elongation of 409 stainless steel plate

The elongation is primarily a measure of the plasticity of the stainless steel sheet - that is, the ability to deform without cracking.

δ= (L-L0)/L0*100%

δ---elongation

L0----The original length of the sample

L----The length of the specimen after tensile cracking

Sheet Tensile Test

The tensile test of the sheet is also called the uniaxial tensile test or abbreviated tensile test. Using the tensile test method, many experimental values for identifying the stamping function of the sheet can be obtained, so it is widely used.

Because of the different experimental intentions, the tensile test method and the obtained experimental values for the evaluation of the stamping function of the sheet are different from the tensile test for the identification of the strength function of the material.
