Re: [MW:8251] Tensile test specimen

Kumar,
 
The basic reason of shape given to the specimen is because spec requires so. It is so to concentrate stress in the region we want to study. If full specimen is of the same size, like reinforcement bars are tested, we wont be able to focus on a specific region to study the mechanical properties as it may break in the grip region and test would be wasted.

Dear peers,
I need some information regarding the shape of the Tensile Test specimen.(As per ASTM A370)
When we are doing the tensile test, why we need to take the sample in the form of Dumbell or Shouldered specimens?
Is the shape is only for the grip purpose?

Thanks and Best regards
