Yield of blacksmith forging

  1. Mar 20, 2017 at 8:01 AM #1
    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?
