stresses induced by quenching
stresses induced by quenching
(OP)
I'm new to FEA but i am doing an analysis on stresses induced during heat treat quenching. I have been using a load on the entire volume of the part and have a temperature constraint on all the surfaces of the part. I adjust the load until i get the correct delta T. I'm not sure the temperature gradient is correct but the results seem to mirror reality. Is there a better way to apply heat to the part? I am using ProMechanica.

The cracking is related to fracture mechanics. Do you have internal voids or something to determine its effect? A simple stress result may not be meaningful. In other words, you could have two same residual stresses and one material would crack while another would not. How would you tell the difference in your model? A simple yield criterion is not going to cut it. I am asking this because if you are new to FEA, you may not be sure of the difference.
From a practical side, if you are getting cracks, why not change the material/alloy?
