Dear sir

Thank you for giving me reference.

Im going through this paper..Bt in that paper damage model is not given..

If you know actual damage criteria please send me...

Thank you..

These fracture parameters were obtained based on a set of quasi-static tensile tests, with smooth and pre-notched round bars at room temperature and elevated temperatures.

You can see that some other researcher used the following values:( D1 D2 D3 D4 D5)

[Borkovec, 2008] 0.25 4.38 -2.68 0.002 0.61

[Varizi, 2010] 0.05 4.22 -2.73 0.0018 0.55

Respectively .

Extensive study was performed by KEYAN in 2016 in his thesis " CALIBRATION OF THE JOHNSON-COOK FAILURE PARAMETERS AS THE CHIP SEPARATION CRITERION IN THE MODELLING OF THE ORTHOGONAL METAL CUTTING PROCESS"

I hope it is useful too you.
