Hello all, Is there a method to validate if our Simufact forming compression test model and results are valid or not? Thanks

  • Hello Christian,
     
    Thank you,
     
    I did verify my model and it seems correct, may I know why there is a difference between the obtained flow stress strain curve vs the material database flow stress strain curve?
     
    Also why are the curves different in global and individual ones in the database. the global shows a peak flow stress of close to 250 Mpa but not same in the individual table?
    Flow curves IN718 powder 0.01 1000c
    Flow curves IN718 powder global
     
    Please find the below plot of flow stress vs strain after doing the test in Simufact forging module, dies with no heat conduction and applied boundary conditions.
    Flow stress vs strain simufact test data
     
    could you please confirm if my model is correct, or if am doing any mistakes please correct me .
     
    Thank you.
