Can Tresca's Law Be Proven Using Yield Application in Blacksmith Forging?

[Jillansts]

How do i find out yield application of hammer hitting a specimen (just like blacksmith did? Since tresca law stated yieldmaterial<yield application to make deformation of specimen, yield of material for example 100MPa (high tempt yield) but yield application=F/A (assume force given is 600Newton, and A is hammer head area (assume 55x60 mm), so the yield of material is only 0,18 MPa, but the actual it does deformed. How can i prove that tresca law is right?

Tresca's law states that the maximum shear stress in a material is equal to the yield strength divided by the square root of 3. In other words, the yield application of hammer hitting a specimen is equal to the yield strength divided by the square root of 3. The yield strength of a material is the maximum amount of stress it can take before it permanently deforms. To prove that Tresca's law is right, you can perform a simple experiment. First, measure the yield strength of the material you are using. Then, apply a known force, such as 600 Newtons, to the specimen with a hammer. Measure how much the specimen deforms. If the deformation is equal to the yield strength divided by the square root of 3, then Tresca's law is correct.
